#27 closed defect (fixed)

unsigned-c-string does not work as advertised

Reported by: sjamaan Owned by: felix winkelmann
Priority: minor Milestone:
Component: compiler Version:
Keywords: ffi, unsigned, strings Cc:
Estimated difficulty:


When trying to call a foreign C function that accepts "unsigned char *" arguments, I get compiler warnings "pointer targets in passing argument N of 'X' differ in signedness".

This is caused because unsigned-c-string(*) results in the same generated code as c-string(*). This happens on Chicken 4 and also on the current version of Chicken 3.
