mkdirat (2)

    NAME

    mkdirat - create a directory relative to a directory file descriptor
     
    

    SYNOPSIS

    #define _ATFILE_SOURCE
    #include <fcntl.h>           /* Definition of AT_* constants */
    #include <sys/stat.h>
    
    int mkdirat(int dirfd, const char *pathname, mode_t mode);
    
     

    DESCRIPTION

    The mkdirat() system call operates in exactly the same way as mkdir(2), except for the differences described in this manual page.

    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 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 pathname is absolute, then dirfd is ignored.  

    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.  

    CONFORMING TO

    POSIX.1-2008.  

    NOTES

    See openat(2) for an explanation of the need for mkdirat().
