From ecf1c6ca5daf0bb8bb5a77167dff8f56cc89417f Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 11 Mar 2008 13:14:16 +0000 Subject: - Added a macro for curl_easy_setopt() that accepts three arguments and simply does nothing with them, just to make sure libcurl users always use three arguments to this function. Due to its use of ... for the third argument, it is otherwise hard to detect abuse. --- include/curl/curl.h | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/curl/curl.h b/include/curl/curl.h index 3027ca06d..4af714291 100644 --- a/include/curl/curl.h +++ b/include/curl/curl.h @@ -1792,8 +1792,16 @@ CURL_EXTERN CURLcode curl_easy_pause(CURL *handle, int bitmask); #include "multi.h" /* the typechecker doesn't work in C++ (yet) */ -#if (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 3)) && !defined(__cplusplus) +#if (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 3)) && \ + !defined(__cplusplus) #include "typecheck-gcc.h" +#else +#if defined(__STDC__) && (__STDC__ >= 1) +/* This preprocessor magic that replaces a call with the exact same call is + only done to make sure application authors use exactly three arguments + to this function. */ +#define curl_easy_setopt(handle,opt,param) curl_easy_setopt(handle,opt,param) +#endif /* __STDC__ >= 1 */ #endif /* gcc >= 4.3 && !__cplusplus */ #endif /* __CURL_CURL_H */ -- cgit v1.2.3
