IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide
Defines a function on request and then remembers the handle.
Can be used to avoid the overhead of defining the function several times in VT_Function.
VT_FuncDef (const char *symname, const char *classname)
Stores the function handle, 0 if not defined yet.
Stores the symbol name.
Stores the class name.
Checks whether the function is already defined or not.
Returns handle as soon as it is available, otherwise 0. Defining the function may be impossible for example, because IntelĀ® Trace Collector was not initialized or ran out of memory.
