Fields

allocate: Option<unsafe extern "C" fn(usize, *mut c_void) -> *mut c_void>

The memory allocation function. See @ref GLFWallocatefun for details about allocation function.

reallocate: Option<unsafe extern "C" fn(*mut c_void, usize, *mut c_void) -> *mut c_void>

The memory reallocation function. See @ref GLFWreallocatefun for details about reallocation function.

deallocate: Option<unsafe extern "C" fn(*mut c_void, *mut c_void)>

The memory deallocation function. See @ref GLFWdeallocatefun for details about deallocation function.

user: *mut c_void

The user pointer for this custom allocator. This value will be passed to the allocator functions.
