33 | /* NOTES: |
||
34 | * 1 - Various functions were adapted from FreeBSD (copyright holders noted above) |
||
35 | * these functions are identified with comments. |
||
36 | * |
||
37 | * 2 - Some of these have since appeared in libc. They remain here for various |
||
38 | * reasons, such as the eventual integration of garbage collection for things |
||
39 | * that allocate memory and don't automatically free it. |
||
40 | * |
||
41 | * 3 - Things that expect a pointer to an allocated string do _no_ sanity checking |
||
42 | * if developing on a simulator with no debugger, take care :) |
