getdtablesize2
Get descriptor table size
Usage
#include <unistd.h>
int
getdtablesize(void);
Library
Standard C Library (libc, -lc)
Overview
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.
Legacy
The getrlimit(2) function returns a value of type rlim_t. This interface, returning an int, may have problems representing appropriate values in the future. Applications should use the getrlimit(2) function instead.
