2025-09-19T17:54:27+00:00

Some of the functions in this file do not follow the normal style. Fix
this so that things are more consistent.

lib: provide function hextoull()

2024-11-13T14:14:23+00:00

We often convert hexadecimal strings to hextoull(). Provide a wrapper
function to simple_strtoull() that does not require specifying the radix.

lib: Add a function to split a string into substrings

2023-01-23T23:11:39+00:00

Some environment variables provide a space-separated list of strings. It
is easier to process these when they are broken out into an array of
strings.

Add a utility function to handle this.

lib: Add a way to find the postiion of a trailing number

2022-04-25T14:00:03+00:00

At present it is not possible to find out which part of the string is the
number part and which is before it. Add a new variant which provides this
feature, so we can separate the two in the caller.

lib: Fix a few bugs in trailing_strtoln()

2022-04-25T14:00:03+00:00

At present this has a minor bug in that it reads the byte before the
start of the string, if it is empty. Also it doesn't handle a
non-numeric prefix which is only one character long.

Fix these bugs with a reworked implementation. Add a test for the second
case. The first one is hard to test.

lib: Correct comment formatting to avoid sphinx problems

2022-04-25T14:00:03+00:00

Tweak a few comments to kep sphinx happy, in case we want to include this
file one day.

Also fix the 'exxamine' typo.

Patch-notes:
This uses:

   sed -i 's/@param \(\S*\)\s*/@\1: /' include/vsprintf.h

to convert the @param to the new format.

2022-04-25T14:00:03+00:00

This function currently has no tests. Add some.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

lib: export vsscanf

2022-01-14T18:16:11+00:00

The function was missing from exports, even though it loooks like the
intent of the implementation in sscanf.c was to have it exported.
