Actually, this is what I have:
in C
double complex a, b, z
int lnchf ip
out = conhyp_ (&a, &b, &z, &lnchf, &ip) ;
In Fortran:
FUNCTION CONHYP (A,B,Z,LNCHF,IP)
INTEGER LNCHF,IP
COMPLEX*16 CHGF,A,B,Z,CONHYP
And what I get is
A= b, B=z (the other values are wrong)
It means that the first variable (here a) is just lost
How can I fix this?
