SDL_EnumerateDirectory

Enumerate a directory through a callback function.

Header File

Defined in <SDL3/SDL_filesystem.h>

Syntax

bool SDL_EnumerateDirectory(const char *path, SDL_EnumerateDirectoryCallback callback, void *userdata);

Function Parameters

const char *	path	the path of the directory to enumerate.
SDL_EnumerateDirectoryCallback	callback	a function that is called for each entry in the directory.
void *	userdata	a pointer that is passed to callback.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

This function provides every directory entry through an app-provided callback, called once for each directory entry, until all results have been provided or the callback returns either SDL_ENUM_SUCCESS or SDL_ENUM_FAILURE.

This will return false if there was a system problem in general, or if a callback returns SDL_ENUM_FAILURE. A successful return means a callback returned SDL_ENUM_SUCCESS to halt enumeration, or all directory entries were enumerated.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL 3.2.0.
