[LCP]passing struct to function

[Tushar_Oza at Dell.com]

Shouldn't you be passing just list_ptr? Why the "ampersand" when making
the call??

I am trying to find what I am doing wrong.  This program compiles with
the warning message:

warning: passing arg 1 of `print_mailing_list' from incompatible pointer
type

When I run the program, the output is:

 f at carlos


#include <stdio.h>
#include <string.h>

struct mailing
{
        char first_name[60];
};

void print_mailing_list(struct mailing *mlist) {
        printf("%s\n", mlist->first_name); }

int main()
{
        struct mailing list =
                {
                        "carlos"
                };


        struct mailing *list_ptr;

        if (strcmp(list.first_name, "carlos") == 0)
                print_mailing_list(&list_ptr);

        return 0;

}
