Hi,
OK, I took a look into the code and I conclude that parm is the tau
specification.
Found in interact.c:
    /* quantreg requires a tau specification */
The tau is the desired quantile (or a list, like you can select when using
the GUI).
About API documentation update, I believe that Allin only writes minimal
documentation in early development of gretl.
Bye,
Hélio

 hello Hélio,
 sorry but this is not C api reference of libgretl you gave me.
 it does not tell me what to put into parm parameter.
 And the online help as i said does not gave me the information about the
 "const char* parm" of the C libgretl library.
 but thanks :-)
