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



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 BSD 4.2).
