Since	17.5

void  chid(string channel_path, int &op_id, int &parm_index, int &vector_index)

void  chid(string op_path, string channel_name, int &op_id, int &parm_index, int &vector_index)

int  chid(int op_id, int parm_index, int vector_index)

Resolves a channel given by a channel path or operator path and returns

its corresponding operator id, parameter id and vector_index through output arguments. Return -1 values on failure. You can also use the last overloaded function that doesn’t take a channel_path to test for validity of the keys. Returns 1 if the ids are valid, otherwise returns 0.
