     int
     closefrom(int fd);

     the per-process file descriptor table.  It	is effectively the same	as
     calling close(2) on each descriptor.

     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     closefrom() will fail if:

     [EBADF]		fd is greater than all open file descriptors.

     [EINTR]		An interrupt was received.

SEE ALSO

     closefrom() is a BSD and Solaris extension.

HISTORY
     The closefrom() function first appeared in	Solaris	9 and has been avail-
     able since	OpenBSD	3.5.
