NetBSD 6.1.5 - man page for closefrom (netbsd section 3)

CLOSEFROM(3)			   BSD Library Functions Manual 		     CLOSEFROM(3)

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.

SEE ALSO
     close(2)
