How to pass user input from gtk to a function ?

[MrNEtBomber]

i want to pass a user input from gtk input box to a function ... i made code below but i had segmentation errors ...so after looking it up i discovred that the line -> "g_signal_connect(but,"clicked",G_CALLBACK(encode(tx1,tx2)),NULL);"
doesnt make a sense so can you help me do it .

this is program source =>

......
//gets the first argument(buf)
tx1=gtk_entry_get_text(GTK_ENTRY(entry));
....
//gets the second argument(pass)
tx2=gtk_entry_get_text(GTK_ENTRY(entry));
.....
//signal to callback funtion encode when button clicked
g_signal_connect(but,"clicked",G_CALLBACK(encode(tx1,tx2)),NULL);
....
//convert const char* to char*
char* ret (const char *bd){
char *c = new char[12];
strcpy(c,bd);
return c;
}
//encode function
char encode(const char ebuf[],const char epass[]) {
//this is what i only wrote and still having the error.
char *buf=ret(ebuf);
char *pass=ret(epass);
}

GTK is not a topic for this group. Did you have a question about the
C++ language?

this is program source =>

You have an error on line 42 of your code. Since many of us do not
know GTK, and none of us know what the context of your snippet is,
we can't help you... we're not psychic.

Provide a minimal compilable example that that exhibits the behavior
in question.

Also, find a group that is more on topic for this question.

I had a problem with my car, but the mechanic was closed. So I asked my
butcher because he uses a car.
