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 er- ror, 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 255 characters, or an en- tire path name exceeded 1023 characters. [ENOENT] A component of the path prefix does not exist. [EACCES] Search permission is denied for a component of the path pre- fix. [ELOOP] Too many symbolic links were encountered in translating the pathname. [EPERM] The path argument contains a byte with the high-order bit set. [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 di- rectory 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 di- rectory 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 al- locating 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.
