prefix string data to string

This method parses a string in the format used by gcc class names The string begins with the length of the string expressed in ascii encoded integer, followed by the character data (no 0 character at the end).

Parameters
ptrpointer to the character data pointer, this pointer is incremented by the parsing.
Returns
a string containing the string data
