Not necessarily, most compilers will optimize if(strlen(file)>0) into the equivalent of if(*file) even at -O0 optimization level (even GCC 4.1 does that according to godbolt.org). It might still be worth doing though for more arcane compilers on platforms that curl build on. > Are you able to turn this into a PR? +1 -- Daniel Gustafsson -- Unsubscribe: https://lists.haxx.se/mailman/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
