unlink - remove directory entry SYNOPSIS
#include <unistd.h> int unlink(const char *path) DESCRIPTION
Unlink removes the entry for the file path from its directory. If this entry was the last link to the file, and no process has the file open, then all resources associated with the file are reclaimed. If, however, the file was open in any process, the actual resource recla- mation is delayed until it is closed, even though the directory entry has disappeared. RETURN VALUE
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] The path name exceeds 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. (Minix-vmd) [EPERM] The named file is a directory. [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. (Minix-vmd) [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
