MKDIR !!!MKDIR NAME SYNOPSIS DESCRIPTION RETURN VALUE ERRORS CONFORMING TO SEE ALSO ---- !!NAME mkdir - create a directory !!SYNOPSIS __#include __''pathname''__, mode_t__ ''mode''__); __ !!DESCRIPTION __mkdir__ 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 __. 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 VALUE __mkdir__ returns zero on success, or -1 if an error occurred (in which case, ''errno'' is set appropriately). !!ERRORS __EPERM__ The filesystem containing ''pathname'' does not support the creation of directories. __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. __EACCES__ The parent directory does not allow write permission to the process, or one of the directories in ''pathname'' did not allow search (execute) permission. __ENAMETOOLONG__ ''pathname'' was too long. __ENOENT__ A directory component in ''pathname'' does not exist or is a dangling symbolic link. __ENOTDIR__ A component used as a directory in ''pathname'' is not, in fact, a directory. __ENOMEM__ Insufficient kernel memory was available. __EROFS__ ''pathname'' refers to a file on a read-only filesystem. __ELOOP__ Too many symbolic links were encountered in resolving ''pathname''. __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. !!CONFORMING TO SVr4, 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__. !!SEE ALSO mkdir(1), chmod(2), mknod(2), mount(2), rmdir(2), stat(2), umask(2), unlink(2) ----
