Header file

Overview
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.
