ANSI_SYNOPSIS
|

|
|
#include <stdio.h>
|
||
|
|
int remove(char *<[filename]>);
|
||
|
|
|
||
|

|
||

|
|
TRAD_SYNOPSIS
|
||
|
|
#include <stdio.h>
|
||
|
|
int remove(<[filename]>)
|
||
|
|
char *<[filename]>;
|
||
|
|
|
||
|
|
int _remove_r(<[reent]>, <[filename]>)
|
||
|
|
struct _reent *<[reent]>;
|
||
|
|
char *<[filename]>;
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
Use <<remove>> to dissolve the association between a particular
|
||
|
|
filename (the string at <[filename]>) and the file it represents.
|
||
|
|
After calling <<remove>> with a particular filename, you will no
|
||
|
|
longer be able to open the file by that name.
|
||
|
|
|
||
|
|
In this implementation, you may use <<remove>> on an open file without
|
||
|
|
error; existing file descriptors for the file will continue to access
|
||
|
|
the file's data until the program using them closes the file.
|
||
|
|
|
||
|
|
The alternate function <<_remove_r>> is a reentrant version. The
|
||
|
|
extra argument <[reent]> is a pointer to a reentrancy structure.
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
<<remove>> returns <<0>> if it succeeds, <<-1>> if it fails.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
ANSI C requires <<remove>>, but only specifies that the result on
|
||
|
|
failure be nonzero. The behavior of <<remove>> when you call it on an
|
||
|
|
open file may vary among implementations.
|
||
|
|
|
||
|
|
Supporting OS subroutine required: <<unlink>>.
