CLOSEFROM(2)		    BSD System Calls Manual		  CLOSEFROM(2)

NAME
     closefrom — delete many descriptors

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     closefrom(int fd);

DESCRIPTION
     The closefrom() system 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.

IMPLEMENTATION NOTES
     The behaviour of the closefrom system call in DragonFly is similar to
     that of SunOS except for error returned in the case of an abort.

RETURN VALUES
     The value of 0 is returned in all cases, or EINTR when an interrupt or
     abort is received.

SEE ALSO
     close(2)

HISTORY
     The closefrom system call appeared in DragonFly 1.2.  It was originally
     introduced in some version of Sun Solaris.

AUTHORS
     This system call is written by Joerg Sonnenberger ⟨joerg@bec.de⟩.
