libposix Copyright (C) 2007 Bahadir Balban Despite the name, this is a library that supports only a small portion of posix functions. Highest priority POSIX functions are: shmat shmget shmdt mmap munmap sbrk read readdir write lseek open close creat mkdir mknod link unlink fork clone execve getpid wait kill getenv setenv Currently supported functions are: shmat shmget shmdt mmap read readdir write lseek open close creat mkdir mknod fork Functions to be supported in the near future are: munmap link unlink getpid execve clone wait kill exit sbrk getenv setenv Other calls: pipe mount unmount swapon New ones will be added as needed.
