# SDL_vsscanf This works exactly like vsscanf() but doesn't require access to a C runtime. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_stdinc.h) ## Syntax ```c int SDL_vsscanf(const char *text, const char *fmt, va_list ap); ``` ## Function Parameters | | | | | ------------ | -------- | --------------------------------------------------------------------- | | const char * | **text** | the string to scan. Must not be NULL. | | const char * | **fmt** | a printf-style format string. Must not be NULL. | | va_list | **ap** | a `va_list` of pointers to values to be filled in with scanned items. | ## Return Value (int) Returns the number of items that matched the format string. ## Remarks Functions identically to [SDL_sscanf](SDL_sscanf)(), except it takes a `va_list` instead of using `...` variable arguments. ## Thread Safety It is safe to call this function from any thread. ## Version This function is available since SDL 3.2.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryStdinc](CategoryStdinc)
