Return Value
_rmtmp returns the number of temporary files closed and deleted.
Remarks
The _rmtmp function cleans up all temporary files in the current directory. The function removes only those files created by tmpfile; use it only in the same directory in which the temporary files were created.
Example
/* TMPFILE.C: This program uses tmpfile to create a
* temporary file, then deletes this file with _rmtmp.
*/
#include <stdio.h>
void main( void )
{
FILE *stream;
char tempstring[] = "String to be written";
int i;
/* Create temporary files. */
for( i = 1; i <= 3; i++ )
{
if( (stream = tmpfile()) == NULL )
perror( "Could not open new temporary file\n" );
else
printf( "Temporary file %d was created\n", i );
}
/* Remove temporary files. */
printf( "%d temporary files deleted\n", _rmtmp() );
}
Output
Temporary file 1 was created
Temporary file 2 was created
Temporary file 3 was created
3 temporary files deleted
