Namemkdir - create a directory
#include <sys/stat.h>#include <sys/types.h> int mkdir(const char *pathname, mode_t mode);
Descriptionmkdir attempts to create a directory named pathname.
mode specifies the permissions to use. It is modified by the process's umask in the usual way: the permissions of the created file are (mode & ~umask).
The newly created directory will be owned by the effective uid 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 gid of the process.
If the parent directory has the set group id bit set then so will the newly created directory.
Return Valuemkdir returns zero on success, or -1 if an error occurred (in which case, errno is set appropriately).
Conforming toSVr4, POSIX, BSD, SYSV, X/OPEN. SVr4 documents additional EIO, EMULTIHOP and ENOLINK error conditions; POSIX.1 omits ELOOP.
There are many infelicities in the protocol underlying NFS. Some of these affect mkdir.
