sin	67157b7c4e	Use SSIZE_MAX for overflow check in parseoffset() ... There's no such thing as OFF_MAX so we can't use that. off_t is signed, so use SSIZE_MAX which will typically match the range of off_t.	2015-11-26 10:35:46 +00:00
FRIGN	8be7c42863	Make strtol() parsing even stricter in parseoffset() ... Be strict about what we pass to it and how we handle errors. The base-check is done by strtol anyway. Also improve error-reporting.	2015-09-30 19:44:11 +01:00
FRIGN	870a75076d	Harden parseoffset() even more ... 1) Check for NULL. 2) Check for empty strings. 3) Clarify error-messages.	2015-09-30 19:44:10 +01:00
FRIGN	64929039e9	Don't forget to scale in parseoffset()	2015-09-30 19:44:10 +01:00
FRIGN	007df69fc5	Add parseoffset() ... This is a utility function to allow easy parsing of file or other offsets, automatically taking in regard suffixes, proper bases and so on, for instance used in split(1) -b or od -j, -N(1). Of course, POSIX is very arbitrary when it comes to defining the parsing rules for different tools. The main focus here lies on being as flexible and consistent as possible. One central utility-function handling the parsing makes this stuff a lot more trivial.	2015-09-30 19:44:10 +01:00
