[3.13] gh-149707: Fix compiler warning in _ctypes_test on strchr() (#149791)
(#149867)
gh-149707: Fix compiler warning in _ctypes_test on strchr() (#149791)
Change my_strchr() return type to "const char*" (add "const").
Fix the compiler warning:
Modules/_ctypes/_ctypes_test.c: In function 'my_strchr':
Modules/_ctypes/_ctypes_test.c:451:12: warning: return discards
'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
451 | return strchr(s, c);
| ^~~~~~
When using C23, strchr(text, ch) return type is "const char*" if text
type is "const char*".
(cherry picked from commit 5465b69255890650df99debb8256e0a7bc68138b)
