C/C++ Calling OBTAIN / IGC0002G

[Cristi Terpea]

I'm trying to call OBTAIN by fetching IGC0002G and executing but keep
getting errors.
This is the code I'm using:

int main (int argc, char *argv[]) {

typedef int OBTAIN(char* ,char*, char*);
#pragma linkage(OBTAIN, OS)
    OBTAIN *OBTAIN_FN;
        char dsname[44], volume[6];
        char search_work_area[140];
        int rc = -1;

    memset(&dsname,' ',44);
        memcpy(&dsname, "IBMUSER.TESTUP", 14);
        memset(&volume,' ', 6);
        memcpy(&volume, "S6SYS1", 6);
        memset(&search_work_area, 0, 140);

    OBTAIN_FN = (OBTAIN *) fetch("IGC0002G");
    printf("Fetched %x\n", OBTAIN_FN);
        rc = OBTAIN_FN(dsname, volume, search_work_area);

        printf("Result: %d\n", rc);
    return 0;
}

and the error I'm getting:
