NAME    [Toc]    [Back]

     closefrom - delete many descriptors

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     int
     closefrom(int fd);

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

     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 indicate
 the error.

ERRORS    [Toc]    [Back]

     closefrom() will fail if:

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

     [EINTR]       An interrupt was received.
