cpp/io/c/remove

Deletes the file identified by character string pointed to by.

If the file is currently open by the current or another process, the behavior of this function is implementation-defined (in particular, POSIX systems unlink the file name, although the file system space is not reclaimed even if this was the last hardlink to the file until the last running process closes the file, Windows does not allow the file to be deleted)

Return value
upon success or non-zero value on error.
