Fixed bug 3696 - SDL_ShowMessageBox displays different error from int…
…ended Mark Callow SDL_ShowMessageBox calls SDL_CaptureMouse which, in the UIKit driver, raises a ?That operation is not supported? error, overwriting the SDL error that an application may be trying to report. This is because UIKit SDL_CaptureMouse returns SDL_Unsupported() which ends up calling SDL_SetError() which has the following code: /* If we are in debug mode, print out an error message */ SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError()); The SDL_GetError call here overwrites the static buffer?.. Although an application can avoid this by using SDL_GetErrorMsg(char* errstr, int maxlen) to avoid the static buffer, SDL should be fixed. The fix is simple. In SDL_SetError change SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", SDL_GetError()); to SDL_LogDebug(SDL_LOG_CATEGORY_ERROR, "%s", error); where error is the pointer to the buffer where it assembled the message.
