Detailed Description

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)

Definition in file SDL_log.h.

Typedef Documentation

typedef void(* SDL_LogOutputFunction)(void *userdata, int category, SDL_LogPriority priority, const char *message)

The prototype for the log output function.

Definition at line 189 of file SDL_log.h.

Enumeration Type Documentation

anonymous enum

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.

Definition at line 64 of file SDL_log.h.

enum SDL_LogPriority

The predefined log priorities.
