The allocated Engine must be freed using FreeEngine;

Returns
Allocated engine.

Definition at line 51 of file engine_sl.cpp.

◆ FreeEngine()

static void FreeEngine ( Engine e)
static

Deallocate an Engine constructed by CallocEngine.

Parameters
eEngine to free.

Definition at line 62 of file engine_sl.cpp.

References free().
