-.TH INTSTRLEN 3 2018-11-05 libsimple
-.SH NAME
-INTSTRLEN \- get the maximum length of an integer string
-.SH SYNOPSIS
-.nf
-#include <libsimple.h>
-
-#ifndef INTSTRLEN
-# define INTSTRLEN(type) /* implementation omitted */
-#endif
-.fi
-.SH DESCRIPTION
-The
-.BR INTSTRLEN ()
-macro assumes
-.I type
-is an integer type, and expends to a value representing
-a number of bytes sufficiently large to store any value
-of the specified integer type as a string without leading
-zeroes or plus sign, and
-.IR "without a terminating NUL byte" ,
-as a constant expression in the type
-.BR size_t ;
-however it is not suitable for
-.BR #if .
-.PP
-The resulting value can depend in either the type is
-signed or unsigned, and can be slightly larger than
-necessary, it can however not be smaller. (For integers
-up to 64 bits, the result is only off by one for signed
-64-bit integer types.)
