NAME
     closefrom - delete many descriptors

SYNOPSIS
     #include <unistd.h>

     int
     closefrom(int fd);

DESCRIPTION
     The closefrom() call deletes all descriptors numbered fd and higher from
     the per-process file descriptor table. It is effectively the same as cal-
     ling close(2) on each descriptor.

RETURN VALUES
     Upon successful completion, a value of 0 is returned. Otherwise, a value
     of -1 is returned and the global integer variable errno is set to indi-
     cate the error.

ERRORS
     closefrom() will fail if:

     [EBADF]	   fd is greater than any open file descriptor.

     [EINTR]	   An interrupt was received.
