FUNCTION

<<remove>>---delete a file's name

INDEX

        remove

ANSI_SYNOPSIS

        #include <stdio.h>

        int remove(char *<[filename]>);

        int _remove_r(void *<[reent]>, char *<[filename]>);

TRAD_SYNOPSIS

        #include <stdio.h>

        int remove(<[filename]>)

        char *<[filename]>;

        int _remove_r(<[reent]>, <[filename]>)

        char *<[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>>.
