Prepares the in-app component of graphics diagnostics to actively capture and record graphics information to a graphics log file.
Syntax
void Init(
std::function<void (int len, wchar_t * pszBuffer)> vsgLogGetter
);
Parameters
vsgLogGetter
A callable entity—such as a function, function pointer, lambda, or function object—that takes as parameters the length of a buffer composed of wchar_t and a pointer to that buffer, and returns void. When invoked, the callable entity determines the file name that will be used to record graphics information, and writes it to the specified buffer before returning.
Remarks
The Init function is called automatically when an instance of the VsgDbg class is constructed by specifying the bDefaultInit parameter of its constructor as true; otherwise, Init must be called explicitly before you can actively capture and record graphics information.
You can finalize and close the active graphics log file by calling UnInit, and then capture and record more graphics information to a new graphics log file by calling Init again. You can repeat this as many times as you want to create several independent graphics log files by using the same VsgDbg instance.
