Manual page for REMOVE(3S)
remove - remove directory entry
SYNOPSIS
#include <stdio.h>
int remove(const char *filename);
DESCRIPTION
Remove
causes the file whose name is the string pointed to by
filename
to be no longer accessible by that name.
A subsequent attempt to open that file using that name
will fail, unless it is created anew.
If this is the only name for the file, and
no process has the file open, the contents
of the file is removed. If a process has the
file open, this process is deferred until the file is closed.
RETURN VALUE
Remove
returns zero if the operation succeeds,
nonzero if it fails.
If it fails,
errno
is set to indicate the cause of the failure.
ERRORS
If any of the following conditions occur,
remove
sets
errno
to the corresponding value:

-

- [ENAMETOOLONG]
