From 47773344fb20bb25b68d5e0b91d76ed781da140d Mon Sep 17 00:00:00 2001 From: Neels Hofmeyr Date: Sun, 5 Sep 2021 18:48:31 +0200 Subject: utils: add osmo_str_to_int() and osmo_str_to_int64() Properly converting a string to an integer while validating against all possible errors is not trivial. It is a recurring theme in code review, and there are places in osmo code that do it wrong. End this by providing a simple API, if for nothing else then as an example of how to use strol() / strtoul() / strtoll() / strtoull() in an airtight way. A subsequent patch, adding stat items to the CTRL interface, uses this to properly validate indexes in CTRL variables and convert them to int.
