GETDTABLESIZE(2)					      GETDTABLESIZE(2)

NAME
       getdtablesize - get descriptor table size

SYNOPSIS
       nfds = getdtablesize()
       int nfds;

DESCRIPTION
       Each  process has a fixed size descriptor table, which is guaranteed to
       have at least 20 slots.	 The  entries  in  the	descriptor  table  are
       numbered	 with  small  integers	starting at 0.	The call getdtablesize
       returns the size of this table.

       Note that POSIX applications have a static  table  size	given  by  the
       constant OPEN_MAX.

SEE ALSO
       close(2), dup(2), open(2), select(2)
