NAME
mkdir - create a directorySYNOPSIS
#include <sys/stat.h> #include <sys/types.h> int mkdir(const char *pathname, mode_t mode);
DESCRIPTION
mkdir() attempts to create a directory named pathname.The parameter mode specifies the permissions to use. It is modified by the process's umask in the usual way: the permissions of the created directory are (mode & ~umask & 0777). Other mode bits of the created directory depend on the operating system. For Linux, see below.
The newly created directory will be owned by the effective user ID of the process. If the directory containing the file has the set-group-ID bit set, or if the filesystem is mounted with BSD group semantics, the new directory will inherit the group ownership from its parent; otherwise it will be owned by the effective group ID of the process.
If the parent directory has the set-group-ID bit set then so will the newly created directory.
RETURN VALUE
mkdir() returns zero on success, or -1 if an error occurred (in which case, errno is set appropriately).ERRORS
- EACCES
- The parent directory does not allow write permission to the process, or one of the directories in pathname did not allow search permission. (See also path_resolution(7).)
- EEXIST
- pathname already exists (not necessarily as a directory). This includes the case where pathname is a symbolic link, dangling or not.
- EFAULT
- pathname points outside your accessible address space.
- ELOOP
- Too many symbolic links were encountered in resolving pathname.
- ENAMETOOLONG
- pathname was too long.
- ENOENT
- A directory component in pathname does not exist or is a dangling symbolic link.
- ENOMEM
- Insufficient kernel memory was available.
- ENOSPC
- The device containing pathname has no room for the new directory.
- ENOSPC
- The new directory cannot be created because the user's disk quota is exhausted.
- ENOTDIR
- A component used as a directory in pathname is not, in fact, a directory.
- EPERM
- The filesystem containing pathname does not support the creation of directories.
- EROFS
- pathname refers to a file on a read-only filesystem.
CONFORMING TO
SVr4, BSD, POSIX.1-2001.NOTES
Under Linux apart from the permission bits, only the S_ISVTX mode bit is honored. That is, under Linux the created directory actually gets mode (mode & ~umask & 01777). See also stat(2).There are many infelicities in the protocol underlying NFS. Some of these affect mkdir().
