Function hyperscan_sys::hs_set_misc_allocator

pub unsafe extern "C" fn hs_set_misc_allocator(
    alloc_func: hs_alloc_t,
    free_func: hs_free_t
) -> hs_error_t

Set the allocate and free functions used by Hyperscan for allocating memory for items returned by the Hyperscan API such as @ref hs_compile_error_t, @ref hs_expr_info_t and serialized databases.

If no misc allocation functions are set, or if NULL is used in place of both parameters, then memory allocation will default to standard methods (such as the system malloc() and free() calls).

This call will override any previous misc allocators that have been set.

Note: the misc allocator may also be set by calling @ref hs_set_allocator().

@param alloc_func A callback function pointer that allocates memory. This function must return memory suitably aligned for the largest representable data type on this platform.

@param free_func A callback function pointer that frees allocated memory.

@return @ref HS_SUCCESS on success, other values on failure.
