| FUNCTION |
| <<remove>>---delete a file's name |
| |
| INDEX |
| remove |
| INDEX |
| _remove_r |
| |
| ANSI_SYNOPSIS |
| #include <stdio.h> |
| int remove(char *<[filename]>); |
| |
| int _remove_r(struct _reent *<[reent]>, 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>>. |
