Returns the state of the byte stream buffer
bool ReadArgs( const char* pszFnName, void* pvFirstArg, bool bPrefixFn );
Name of add-in function whose arguments are being converted to a byte stream.
Address of the first argument to the add-in function. This pointer is used to traverse the argument stack, using the add-in function's registered definition to interpret the items in the stack.
If true, the name of the function will be prefixed to the byte stream. This is useful if a single cache is used for more than one add-in function. If false, then the function is not prefixed. This is appropriate if each add-in function uses its own cache.
This method iterates through the arguments of an add-in function, and writes their values to a single continuous byte stream, optionally prefixed by the name of the add-in function.
