remove() -- General Function (libc)

Remove a file
#include <stdio.h>
int
remove(filename)
const char *filename;

remove() breaks the link between  between filename and the actual file that
it represents.   In effect, it removes a file.   Thereafter, any attempt to
use filename to  open that file will fail.  It  is equivalent to the system
call unlink().

remove() will remove a file  that is currently open.  remove() returns zero
if it could remove filename, and nonzero if it could not.

Example

This example removes the file named on the command line.

#include <stdio.h>
#include <stdlib.h>

main(argc,argv)
int argc, char *argv[])
{
    if(argc != 1) {
        fprintf(stderr, "usage: remove filename\n");
        exit(EXIT_FAILURE);
    }

    if(remove(argv[1])) {
        perror("remove failed");
        exit(EXIT_FAILURE);
    }
    return(EXIT_SUCCESS);
}
