NAME
     getdtablesize - get file descriptor table size

SYNOPSIS
     #include <unistd.h>
     int getdtablesize(void);

DESCRIPTION
     getdtablesize returns the maximum number of file descriptors that the
     calling process can open.  The related getdtablehi(3C) function returns

     of {OPEN_MAX} in intro(2) provides more information about how file
     descriptors are allocated and the various limits imposed on their use.
