- touch() - Create a file, or update mtime. Errors on stderr - makedir() - Create directory, like mkdir(). Errors on stderr - makefifo() - Create a FIFO, like mkfifo(). Errors on stderr - erase() - Erase file/directory with remove(). Errors on stderr - chardev() - Create character device - blkdev() - Create block device - S_ISEXEC() - Mysteriously missing from GLIBC - UNUSED() - Shorter and more readable version of __attribute__ ((unused)) Signed-off-by: Joachim Nilsson <troglobit@gmail.com>
