◆ config_parse_unsigned_long_opt()

static ssize_t config_parse_unsigned_long_opt	(	const char *	name,
		const char *	str,
		size_t	min,
		size_t	max
	)

static

Parse string to unsigned long and ensure it falls within min & max bounds.

Maximum value is limited to maximum positive number or type ssize_t.

Parameters

name	Name of parameter being parsed.
str	String to parse into unsigned long.
min	Minumum bound for parsed unsigned long.
max	Maximum bound for parsed unsigned long.

Returns: Returns parsed unsigned long if it falls within min & max bounds. Otherwise an error message is printed to stderr, and -1 is returned.
