GETDTABLESIZE(2)	   Linux Programmer's Manual	      GETDTABLESIZE(2)

NAME
       getdtablesize - get descriptor table size

SYNOPSIS
       #include <unistd.h>

       int getdtablesize(void);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       getdtablesize(): _BSD_SOURCE || _XOPEN_SOURCE >= 500

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.

ERRORS
       On Linux, getdtablesize() can return any of the	errors	described  for
       getrlimit(2); see NOTES below.

CONFORMING TO
       SVr4,  4.4BSD  (the getdtablesize() function first appeared in 4.2BSD).
       It is not  specified  in	 POSIX.1-2001;	portable  applications	should
       employ sysconf(_SC_OPEN_MAX) instead of this call.

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).

       close(2), dup(2), getrlimit(2), open(2)
