(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)


Get the last error message that was set for the current thread.

Header File

Defined in SDL_error.h, but apps should only #include "SDL.h"!


char * SDL_GetErrorMsg(char *errstr, int maxlen);

Function Parameters

errstr A buffer to fill with the last error message that was set for the current thread
maxlen The size of the buffer pointed to by the errstr parameter

Return Value

Returns the pointer passed in as the errstr parameter.


This allows the caller to copy the error string into a provided buffer, but otherwise operates exactly the same as SDL_GetError().


This function is available since SDL 2.0.14.
