Description

Registers the initialization callback function.

If this API is called before aclInit, the callback function is called during initialization. If this API is called after aclInit, the callback function is called immediately upon registration.

Prototype

aclError aclInitCallbackRegister(aclRegisterCallbackType type, aclInitCallbackFunc cbFunc, void *userData)

Parameters

Parameter	Input/Output	Description
type	Input	Registration type, which is distinguished by function. For details, see aclRegisterCallbackType.
cbFunc	Input	Initialization callback function. Prototype: typedef aclError (aclInitCallbackFunc)(const char configStr, size_t len, void userData); configStr* must be the same as the content of the JSON file in the aclInit API. len indicates the length of the JSON file content, in bytes.
userData	Input	Pointer to the user data to be passed to the callback function.

Parameter

Input/Output
