.Dd December 11, 1993 .Dt MKDIR 2 .Os BSD 4.2 .Sh NAME .Nm mkdir .Nd make a directory file .Sh LIBRARY .Lb libc .Sh SYNOPSIS .Fd #include <sys/types.h> .Fd #include <sys/stat.h> .Ft int .Fn mkdir "const char *path" "mode_t mode" .Sh DESCRIPTION The directory .Fa path is created with the access permissions specified by .Fa mode and restricted by the .Xr umask 2 of the calling process.
p 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. .Sh RETURN VALUES A 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in .Va errno . .Sh ERRORS .Fn Mkdir will fail and no directory will be created if: l -tag -width Er t Bq Er ENOTDIR A component of the path prefix is not a directory. t Bq Er ENAMETOOLONG A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. t Bq Er ENOENT A component of the path prefix does not exist. t Bq Er EACCES Search permission is denied for a component of the path prefix. t Bq Er ELOOP Too many symbolic links were encountered in translating the pathname. t Bq Er EROFS The named file resides on a read-only file system. t Bq Er EEXIST The named file exists. t Bq Er ENOSPC The new directory cannot be created because there is no space left on the file system that will contain the directory. t Bq Er ENOSPC There are no free inodes on the file system on which the directory is being created. t Bq Er 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. t Bq Er EDQUOT The user's quota of inodes on the file system on which the directory is being created has been exhausted. t Bq Er EIO An I/O error occurred while making the directory entry or allocating the inode. t Bq Er EIO An I/O error occurred while reading from or writing to the file system. t Bq Er EFAULT .Fa Path points outside the process's allocated address space. .El .Sh SEE ALSO .Xr chmod 2 , .Xr stat 2 , .Xr umask 2 .Sh STANDARDS The .Fn mkdir function call is expected to conform to .St -p1003.1-90 .
