SDL_RWFromFP
Use this function to create an SDL_RWops structure from a standard I/O file pointer (stdio.h's FILE*).
Contents
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.
Code Examples
FILE *fp = fopen("myfile.dat", "rb");
SDL_RWops *rw = SDL_RWFromFP(fp, SDL_TRUE);
/* Do things with rw... */
SDL_RWclose(rw); /* Automatically does an fclose(fp) in this case */
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.
