SDL_RWFromFP

Use this function to create an SDL_RWops structure from a standard I/O file pointer (stdio.h's FILE*).

Syntax

SDL_RWops* SDL_RWFromFP(void * fp,
                        SDL_bool autoclose);

Function Parameters

fp

the FILE* that feeds the SDL_RWops stream

autoclose

SDL_TRUE to close the FILE* when closing the SDL_RWops, SDL_FALSE to leave the FILE* open when the RWops is closed

Return Value

Returns a pointer to the SDL_RWops structure that is created, or NULL on failure; call SDL_GetError() for more information.

Remarks

This function is not available on Windows, since files opened in an application on that platform cannot be used by a dynamically linked library.

On some platforms, the first parameter is a void*, on others, it's a FILE*, depending on what system headers are available to SDL. It is always intended to be the FILE* type from the C runtime's stdio.h.

Version

This function is available since SDL 2.0.0.
