The predefined log priorities. More... | |
Simple log messages with categories and priorities.
By default logs are quiet, but if you're debugging SDL you might want:
SDL_LogSetAllPriority(SDL_LOG_PRIORITY_WARN);
Here's where the messages go on different platforms: Windows: debug output stream Android: log output Others: standard error output (stderr)

#define SDL_MAX_LOG_MESSAGE 4096 |
typedef void( * SDL_LogOutputFunction) (void *userdata, int category, SDL_LogPriority priority, const char *message) |
The prototype for the log output callback function.
This function is called by SDL when there is new text to be logged.
userdata | what was passed as userdata to SDL_LogSetOutputFunction() |
category | the category of the message |
priority | the priority of the message |
message | the message being output |
enum SDL_LogCategory |
The predefined log categories.
By default the application category is enabled at the INFO level, the assert category is enabled at the WARN level, test is enabled at the VERBOSE level and all other categories are enabled at the CRITICAL level.
