The iniparser.c file used to build libiniparser.so.0 defines iniparser_set with the same parameters as the iniparser_setstring function declared in iniparser.h, but does not define iniparser_setstring. This means it is impossible to cleanly build any source using these functions against libiniparser.
Created attachment 189690 [details, diff] Patch to fix the header to reflect the implementation Patch which changes the header to reflect the current state of the source. The documentation is also changed as looking in the source indicates that it was incorrect.
Applied with rev-bump.
