Expand description

Enumerate a directory through a callback function.

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.

§Parameters

  • path: the path of the directory to enumerate.
  • callback: a function that is called for each entry in the directory.
  • userdata: a pointer that is passed to callback.

§Return value

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

§Availability

This function is available since SDL 3.2.0.
