NAME

       getdtablesize - get descriptor table size

SYNOPSIS

       #include <unistd.h>

       int getdtablesize(void);

DESCRIPTION

       getdtablesize()  returns the maximum number of files a process can have
       open, one more than the largest possible value for a file descriptor.

RETURN VALUE

       The current limit on the number of open files per process.

NOTES

       getdtablesize() is implemented as a libc library  function.  The  glibc
       version calls getrlimit(2) and returns the current RLIMIT_NOFILE limit,
       or OPEN_MAX when that fails.   The  libc4  and  libc5  versions  return
       OPEN_MAX (set to 256 since Linux 0.98.4).

CONFORMING TO

       SVr4, 4.4BSD (the getdtablesize() function first appeared in 4.2BSD).
