Hello sir,
I Got a code from asktom site in pro*c that unloads the data from oracle to flat file. while running the program i am getting some warings and 1 error.anyhow exe is getting formed.when i execute the exe it is giving core dump. can you please look into the coad let me know the problem.
Advance thanks for solution.
Here i am pasting the code
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define MAX_VNAME_LEN 30
#define MAX_INAME_LEN 30
#define vstrcpy( a, b )
(strcpy( a.arr, b ), a.len = strlen( a.arr ), a.arr)

I run the file as
make -f demo_proc.mk build INAME=flat1.pc EXE=flat1.exe OBJS=flat1.o
Here demo proc i copied from oracle_home and flat1.pc is the code i pasted above.
The errors i am getting are
