#include <sys/stat.h> int mkdirat(int dirfd, const char *pathname, mode_t mode); |
If the pathname given in pathname is relative, then it is interpreted relative to the directory referred to by the file descriptor dirfd (rather than relative to the current working directory of the calling process, as is done by mkdir(2) for a relative pathname).
If the pathname given in pathname is relative and dirfd is the special value AT_FDCWD, then pathname is interpreted relative to the current working directory of the calling process (like mkdir(2)).
If the pathname given in pathname is absolute, then dirfd is ignored.
