Functions
int	strtolb (const char *const str, const long min, const long max, void *const p, const int ps)
	Attempts to parse the given string as a long using strtol. If the parsed value is within the given range, it is stored in the given pointer using memcpy, which results in a type-agnostic function. The size of the destination type must be provided in bytes. The destination is only updated if the parsed value is within the given range. The caller should take care to ensure the destination type is large enough to store the parsed value.

Function Documentation

strtolb()

int strtolb	(	const char *	str,
		long	min,
		long	max,
		void *	p,
		int	ps )

Attempts to parse the given string as a long using strtol. If the parsed value is within the given range, it is stored in the given pointer using memcpy, which results in a type-agnostic function. The size of the destination type must be provided in bytes. The destination is only updated if the parsed value is within the given range. The caller should take care to ensure the destination type is large enough to store the parsed value.

Parameters

str	string to parse
min	minimum value (inclusive) supported by the destination type
max	maximum value (inclusive) supported by the destination type
p	pointer to store the parsed value
ps	size of the destination type in bytes

Returns

0 on success, non-zero on failure
