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 calling close(2) on each descriptor.

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.

ERRORS
     closefrom() will fail if:

     [EBADF]		fd is invalid.

     [EINTR]		An interrupt was received.
