Function PHYSFS_getSearchPathCallback 

pub unsafe extern "C" fn PHYSFS_getSearchPathCallback(
    c: PHYSFS_StringCallback,
    d: *mut c_void,
)

\fn void PHYSFS_getSearchPathCallback(PHYSFS_StringCallback c, void *d) \brief Enumerate the search path, using an application-defined callback.

Internally, PHYSFS_getSearchPath() just calls this function and then builds a list before returning to the application, so functionality is identical except for how the information is represented to the application.

Unlike PHYSFS_getSearchPath(), this function does not return an array. Rather, it calls a function specified by the application once per element of the search path:

\code

static void printSearchPath(void *data, const char *pathItem) { printf(“[%s] is in the search path.\n”, pathItem); }

// … PHYSFS_getSearchPathCallback(printSearchPath, NULL); \endcode

Elements of the search path are reported in order search priority, so the first archive/dir that would be examined when looking for a file is the first element passed through the callback.

\param c Callback function to notify about search path elements. \param d Application-defined data passed to callback. Can be NULL.
