unlink(2)							     unlink(2)

Name
       unlink - remove directory entry

Syntax
       unlink(path)
       char *path;

Description
       The system call 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
       reclamation  is	delayed	 until it is closed, even though the directory
       entry has disappeared.

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.

Diagnostics
       The system call succeeds unless:

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

       [ENOENT]	      The named file does not exist or path points to an empty
		      string and the environment  defined  is  POSIX  or  SYS‐
		      TEM_FIVE.

       [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.

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

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

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

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

       [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an
		      entire pathname exceeded 1023 characters.

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

       [EPERM]	      The named file is a directory  and  the  environment  is
		      defined is POSIX.

       [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.

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

       [ETIMEDOUT]    A connect	 request  or  remote  file  operation  failed,
		      because  the  connected  party  did not properly respond
		      after a period of time that is dependent on the communi‐
		      cations protocol.

       [ETXTBSY]      The  named  file	is the last link to a shared text exe‐
		      cutable and the environment defined  is  POSIX  or  SYS‐
		      TEM_FIVE.

Environment
       Differs	from the System V definition in that ELOOP is a possible error
       condition.
