mkdir(3)
NAME
mkdir − make a directory file
SYNTAX
mkdir(path, mode)
char *path;
int mode;
DESCRIPTION
The mkdir subroutine creates a new directory file with name path. The mode of the new file is initialized from mode. The protection part of the mode is modified by the process’s mode mask. For further information, see umask(2).
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.
The low-order 9 bits of mode are modified by the process’s file mode creation mask: all bits set in the process’s file mode creation mask are cleared. For further information, see umask(2).
RETURN VALUE
A 0 return value indicates success. A −1 return value indicates that the directory could not be created.
DIAGNOSTICS
The mkdir subroutine will fail if:
[EACCES] Permission to make the directory was denied.
[ENOEXEC] Could not exec "/bin/mkdir".
