Standard C Library Functions getdtablesize(3C)
NAME
getdtablesize - get the file descriptor table size
SYNOPSIS
#include
int getdtablesize(void);
DESCRIPTION
The getdtablesize() function is equivalent to getrlimit(2)
with the RLIMITNOFILE option.
RETURN VALUES
The getdtablesize() function returns the current soft limit
as if obtained from a call to getrlimit() with the
RLIMITNOFILE option.
ERORS
No errors are defined.
USAGE
There is no direct relationship between the value returned
by getdtablesize() and OPENMAX defined in .
Each process has a file 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
getdtablesize() function returns the current maximum size of
this table by calling the getrlimit() function.
