2684 6147 d 10 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2682 6147 d 16 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 6147 d 17 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6147 d 17 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
 
2678 6153 d 12 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
 
2677 6153 d 13 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
 
2676 6153 d 20 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2674 6154 d 8 h jermar /trunk/uspace/ Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3.
 
2671 6154 d 9 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.  
2670 6158 d 8 h jermar /trunk/uspace/ Move the open(), read() and write() provided by streams.c away so that
these functions won't clash with the real open(), read() and write(), which are
soon to be provided by a libvfs library. Applications can now use open_stdin(),
open_stdout(), read_stdin() and write_stdout(). Later, there might be an option
of providing a custom console file system, which will work similarly to how
streams' open(), read() and write() worked.
 
2668 6158 d 8 h jermar /trunk/uspace/lib/libc/include/io/ Remove file.h.  
2662 6161 d 8 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 6161 d 10 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().
 
2640 6172 d 6 h cejka /trunk/uspace/lib/libc/ Function strncmp() added to libc.  
2637 6180 d 10 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2635 6182 d 10 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2622 6190 d 16 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2621 6192 d 14 h jermar /trunk/uspace/ Modify the async framework to make use of all six syscall arguments.
Supply user-friendly macros as in previous cases.
 
2619 6194 d 8 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().
 
2618 6194 d 21 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.
