file will be #included AFTER <malloc.h>. This is needed only if |
your system defines a struct mallinfo that is incompatible with the |
standard one declared here. Otherwise, you can include this file |
INSTEAD of your system system <malloc.h>. At least on ANSI, all |
declarations should be compatible with system versions |

malloc(size_t n) |
Returns a pointer to a newly allocated chunk of at least n bytes, or |
null if no space is available, in which case errno is set to ENOMEM |
on ANSI C systems. |
If n is zero, malloc returns a minimum-sized chunk. (The minimum |
size is 16 bytes on most 32bit systems, and 32 bytes on 64bit |
systems.) Note that size_t is an unsigned type, so calls with |
arguments that would be negative if signed are interpreted as |
requests for huge amounts of space, which will often fail. The |
maximum supported value of n differs across systems, but is in all |
cases less than the maximum representable value of a size_t. |

The returned pointer may or may not be the same as p. The algorithm |
prefers extending p in most cases when possible, otherwise it |
employs the equivalent of a malloc-copy-free sequence. |
If p is null, realloc is equivalent to malloc. |
If space is not available, realloc returns null, errno is set (if on |
ANSI) and p is NOT freed. |
if n is for fewer bytes than already held by p, the newly unused |
space is lopped off and freed if possible. realloc with a size |
argument of zero (re)allocates a minimum-sized chunk. |

not a power of two, the nearest greater power is used. |
8-byte alignment is guaranteed by normal malloc calls, so don't |

long as the value is meaningful), and returns 1 if successful else |

independent_calloc(size_t n_elements, size_t element_size, void* chunks[]); |
independent_calloc is similar to calloc, but instead of returning a |
single cleared space, it returns an array of pointers to n_elements |
independent elements that can hold contents of size elem_size, each |
of which starts out cleared, and can be independently freed, |
realloc'ed etc. The elements are guaranteed to be adjacently |
allocated (this is not guaranteed to occur with multiple callocs or |
mallocs), which may also improve cache locality in some |
applications. |
The "chunks" argument is optional (i.e., may be null, which is |
probably the most typical usage). If it is null, the returned array |
is itself dynamically allocated and should also be freed when it is |
no longer needed. Otherwise, the chunks array must be of at least |
n_elements in length. It is filled in with the pointers to the |
chunks. |
In either case, independent_calloc returns this pointer array, or |
null if the allocation failed. If n_elements is zero and "chunks" |
is null, it returns a chunk representing an array with zero elements |
(which should be freed if not wanted). |
Each element must be individually freed when it is no longer |
needed. If you'd like to instead be able to free all at once, you |
should instead use regular calloc and assign pointers into this |
space to represent elements. (In this case though, you cannot |
independently free elements.) |
independent_calloc simplifies and speeds up implementations of many |
kinds of pools. It may also be useful when constructing large data |
structures that initially have a fixed number of fixed-sized nodes, |
but the number is not known at compile time, and some of the nodes |
may later need to be freed. For example: |
struct Node { int item; struct Node* next; }; |
struct Node* build_list() { |
struct Node** pool; |
int n = read_number_of_nodes_needed(); |
if (n <= 0) return 0; |
pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0); |
if (pool == 0) die(); |
// organize into a linked list... |
struct Node* first = pool[0]; |
for (i = 0; i < n-1; ++i) |
pool[i]->next = pool[i+1]; |
free(pool); // Can now free the array (or not, if it is needed later) |
return first; |
} |
*/ |

/* |
independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]); |
independent_comalloc allocates, all at once, a set of n_elements |
chunks with sizes indicated in the "sizes" array. It returns |
an array of pointers to these elements, each of which can be |
independently freed, realloc'ed etc. The elements are guaranteed to |
be adjacently allocated (this is not guaranteed to occur with |
multiple callocs or mallocs), which may also improve cache locality |
in some applications. |
The "chunks" argument is optional (i.e., may be null). If it is null |
the returned array is itself dynamically allocated and should also |
be freed when it is no longer needed. Otherwise, the chunks array |
must be of at least n_elements in length. It is filled in with the |
pointers to the chunks. |
In either case, independent_comalloc returns this pointer array, or |
null if the allocation failed. If n_elements is zero and chunks is |
null, it returns a chunk representing an array with zero elements |
(which should be freed if not wanted). |
Each element must be individually freed when it is no longer |
needed. If you'd like to instead be able to free all at once, you |
should instead use a single regular malloc, and assign pointers at |
particular offsets in the aggregate space. (In this case though, you |
cannot independently free elements.) |
independent_comallac differs from independent_calloc in that each |
element may have a different size, and also that it does not |
automatically clear elements. |
independent_comalloc can be used to speed up allocation in cases |
where several structs or objects must always be allocated at the |
same time. For example: |
struct Head { ... } |
struct Foot { ... } |
void send_message(char* msg) { |
int msglen = strlen(msg); |
size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) }; |
void* chunks[3]; |
if (independent_comalloc(3, sizes, chunks) == 0) |
die(); |
struct Head* head = (struct Head*)(chunks[0]); |
char* body = (char*)(chunks[1]); |
struct Foot* foot = (struct Foot*)(chunks[2]); |
// ... |
} |
In general though, independent_comalloc is worth using only for |
larger values of n_elements. For small values, you probably won't |
detect enough difference from series of malloc calls to bother. |
Overuse of independent_comalloc can increase overall memory usage, |
since it cannot reuse existing noncontiguous small chunks that |
might be available for some of the elements. |

malloc_trim(size_t pad); |
If possible, gives memory back to the system (via negative arguments |
to sbrk) if there is unused memory at the `high' end of the malloc |
pool or in unused MMAP segments. You can call this after freeing |
large blocks of memory to potentially reduce the system-level memory |
requirements of a program. However, it cannot guarantee to reduce |
memory. Under some allocation patterns, some large free blocks of |
memory will be locked between two used chunks, so they cannot be |
given back to the system. |
The `pad' argument to malloc_trim represents the amount of free |
trailing space to leave untrimmed. If this argument is zero, only |
the minimum amount of memory to maintain internal data structures |
will be left. Non-zero arguments can be supplied to maintain enough |
trailing space to service future expected allocations without having |
to re-obtain memory from the system. |
Malloc_trim returns 1 if it actually released any memory, else 0. |

overwriting other allocated objects. This is not a particularly great |
programming practice. malloc_usable_size can be more useful in |
debugging and assertions, for example: |
p = malloc(n); |

Prints on stderr the amount of space obtained from the system (both |

current if malloc_trim and/or munmap got called), and the current |
number of bytes allocated via malloc (or realloc, etc) but not yet |
freed. Note that this is the number of bytes allocated, not the |
number requested. It will be larger than the number requested |
because of alignment and bookkeeping overhead. Because it includes |
alignment wastage as being in use, this figure may be greater than |
zero even when no user-level chunks are allocated. |
The reported current and maximum system memory can be inaccurate if |
a program makes other calls to system memory allocation functions |
(normally sbrk) outside of malloc. |
malloc_stats prints only the most commonly interesting statistics. |
More information can be obtained by calling mallinfo. |
