remove()

NAME

remove() - remove file from a directory

SYNOPSIS

#include <unistd.h>


int remove (const char *path)

DESCRIPTION

The remove(3) function removes the link named by path from its directory and decrements the link count of the file which was referenced by the link. If that decrement reduces the link count of the file to zero, and no process has the file open, then all resources associated with the file are reclaimed. If one or more process have the file open when the last link is removed, the link is removed, but the removal of the file is delayed until all references to it have been closed.

Calling remove(3) with a directory is not supported.

This function is identical to unlink(2).

RETURN VALUES

Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.
