MKDIR(2)			     BSD System Calls Manual				 MKDIR(2)

NAME
     mkdir -- make a directory file

SYNOPSIS
     #include <sys/types.h>
     #include <sys/stat.h>

     int
     mkdir(const char *path, mode_t mode);

DESCRIPTION
     The directory path is created with the access permissions specified by mode and restricted
     by the umask(2) of the calling process.

     The directory's owner ID is set to the process's effective user ID.  The directory's group
     ID is set to that of the parent directory in which it is created.

RETURN VALUES
     A 0 return value indicates success.  A -1 return value indicates an error, and an error code
     is stored in errno.

ERRORS
     Mkdir() will fail and no directory will be created if:

     [ENOTDIR]		A component of the path prefix is not a directory.

     [ENAMETOOLONG]	A component of a pathname exceeded {NAME_MAX} characters, or an entire
			path name exceeded {PATH_MAX} characters.

     [ENOENT]		A component of the path prefix does not exist.

     [EACCES]		Search permission is denied for a component of the path prefix.

     [ELOOP]		Too many symbolic links were encountered in translating the pathname.

     [EROFS]		The named file resides on a read-only file system.

     [EEXIST]		The named file exists.

     [ENOSPC]		The new directory cannot be created because there is no space left on the
			file system that will contain the directory.

     [ENOSPC]		There are no free inodes on the file system on which the directory is
			being created.

     [EDQUOT]		The new directory cannot be created because the user's quota of disk
			blocks on the file system that will contain the directory has been
			exhausted.

     [EDQUOT]		The user's quota of inodes on the file system on which the directory is
			being created has been exhausted.

     [EIO]		An I/O error occurred while making the directory entry or allocating the
			inode.

     [EIO]		An I/O error occurred while reading from or writing to the file system.

     [EFAULT]		Path points outside the process's allocated address space.
