getdtablesize − get descriptor table size
#include <unistd.h>
int getdtablesize(void);
getdtablesize returns the maximum number of files a process can have open, one more than the largest possible value for a file descriptor.
The current limit on the number of open files per process.
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).
SVr4, 4.4BSD (the getdtablesize function first appeared in BSD 4.2).
