NAME¶
mkdirat - create a directory relative to a directory file descriptorSYNOPSIS¶
#include <fcntl.h> /* Definition of AT_* constants */ #include <sys/stat.h>int mkdirat(int dirfd, const char *pathname, mode_t mode);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
- Since glibc 2.10:
- _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
- Before glibc 2.10:
- _ATFILE_SOURCE
DESCRIPTION¶
The mkdirat() system call operates in exactly the same way as mkdir(2), except for the differences described in this manual page.RETURN VALUE¶
On success, mkdirat() returns 0. On error, -1 is returned and errno is set to indicate the error.ERRORS¶
The same errors that occur for mkdir(2) can also occur for mkdirat(). The following additional errors can occur for mkdirat():- EBADF
- dirfd is not a valid file descriptor.
- ENOTDIR
- pathname is relative and dirfd is a file descriptor referring to a file other than a directory.
VERSIONS¶
mkdirat() was added to Linux in kernel 2.6.16; library support was added to glibc in version 2.4.CONFORMING TO¶
