unlink

UNLINK(2)						      BSD System Calls Manual							 UNLINK(2)

NAME

     unlink -- remove directory entry

SYNOPSIS

     #include <unistd.h>

     int
     unlink(const char *path);

DESCRIPTION

     The unlink() function removes the link named by path from its directory and decrements the link count of the file which was referenced by the
     link.  If that decrement reduces the link count of the file to zero, and no process has the file open, then all resources associated with the
     file are reclaimed.  If one or more process have the file open when the last link is removed, the link is removed, but the removal of the
     file is delayed until all references to it have been closed.

RETURN VALUES

     Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

     The unlink() succeeds unless:

     [ENOTDIR]		A component of the path prefix is not a directory.

     [ENAMETOOLONG]	A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters.

     [ENOENT]		The named file does not exist.

     [EACCES]		Search permission is denied for a component of the path prefix.

     [EACCES]		Write permission is denied on the directory containing the link to be removed.

     [ELOOP]		Too many symbolic links were encountered in translating the pathname.

     [EPERM]		The named file is a directory and the effective user ID of the process is not the super-user.

     [EPERM]		The directory containing the file is marked sticky, and neither the containing directory nor the file to be removed are
			owned by the effective user ID.

     [EBUSY]		The entry to be unlinked is the mount point for a mounted file system.

     [EIO]		An I/O error occurred while deleting the directory entry or deallocating the inode.

     [EROFS]		The named file resides on a read-only file system.

     [EFAULT]		Path points outside the process's allocated address space.

SEE ALSO

     close(2), link(2), rmdir(2) symlink(7)

HISTORY

     An unlink() function call appeared in Version 6 AT&T UNIX.
