prototype in json-maker.h is `char* json_objOpen( char* dest, char const* name, size_t* remLen );` but the sample code is... `dest = json_objOpen( dest, name ); ` also noticed the code looked suspiciously reactionary to buffer overflow at... ``` char buff[512]; int len = data_to_json( buff, &data ); if( len >= sizeof buff ) { fprintf( stderr, "%s%d%s%d\n", "Error. Len: ", len, " Max: ", (int)sizeof buff - 1 ); return EXIT_FAILURE; } ``` betting that issue was fixed, but the sample code wasn't updated.
