<TITLE>mkdir</TITLE> <body bgcolor="#ffffcc"> <hr> <pre> <h3>MKDIR(2) Linux Programmer's Manual MKDIR(2) </h3> <h3>NAME </h3> mkdir - create a directory <h3>SYNOPSIS </h3> #include <sys/types.h> #include <fcntl.h> #include <unistd.h> int mkdir(const char *pathname, mode_t mode); <h3>DESCRIPTION </h3> 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 & ~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. <h3>RETURN VALUE </h3> mkdir returns zero on success, or -1 if an error occurred (in which case, errno is set appropriately). <h3>ERRORS </h3> EEXIST pathname already exists (not necessarily as a directory). EFAULT pathname points outside your accessible address space. EACCES The parent directory does not allow write permis- sion 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. <h3>Linux 1.0 29 March 1994 1 </h3> <h3>MKDIR(2) Linux Programmer's Manual MKDIR(2) </h3> EROFS pathname refers to a file on a read-only filesystem and write access was requested. ELOOP pathname contains a reference to a circular sym- bolic link, ie a symbolic link whose expansion con- tains a reference to itself. 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. <h3>CONFORMING TO </h3><h3>BUGS </h3> In some older versions of Linux (for example, 0.99pl7) all the normal filesystems sometime allow the creation of two files in the same directory with the same name. This occurs only rarely and only on a heavily loaded system. It is believed that this bug was fixed in the Minix filesystem in Linux 0.99pl8 pre-release; and it is hoped that it was fixed in the other filesystems shortly after- wards. There are many infelicities in the protocol underlying NFS. </pre> <hr> <h3>SEE ALSO </h3><p> <a href=read.htm>read</a>, <a href=write.htm>write</a>, <a href=fcntl.htm>fcntl</a>, <a href=close.htm>close</a>, <a href=unlink.htm>unlink</a>, <a href=open.htm>open</a>, <a href=mknod.htm>mknod</a>, <a href=stat.htm>stat</a>, <a href=umask.htm>umask</a>, <a href=mount.htm>mount</a>, <a href=socket.htm>socket</a>, <a href=socket.htm>socket</a>, <pre> <h3>Linux 1.0 29 March 1994 2 </h3> </pre> <P> <hr> <p> <center> <table border=2 width=80%> <tr align=center> <td width=25%> <a href=../index.htm>Top</a> </td><td width=25%> <a href=../master_index.html>Master Index</a> </td><td width=25%> <a href=../SYNTAX/keywords.html>Keywords</a> </td><td width=25%> <a href=../FUNCTIONS/index.htm>Functions</a> </td> </tr> </table> </center> <p> <hr> This manual page was brought to you by <i>mjl_man V-2.0</i>
