hi
i m declaring a structure globally & there is func1 & main.
i m assigning the value to variable(this is a pointer) of structure in
fun1 & want to print it in main.
this is same kind of problem not the actual code. pls help.


static struct des_rbuf{
unsigned int ind;
long long buf_adr;
unsigned int len;
}desc_rbuf[512];

static l;
int main()
{
fun1();
for(p=0;p<l;p++ )
PRINT("%u\t\t\t \t%x\t\t\t
%u",desc_rbuf[p].ind,desc_rbuf[p].buf_adr,desc_r buf[p].len);
//here it is printing all the values 0
}

fun1
{
desc_rbuf[l].ind=i;
desc_rbuf[l].buf_adr=(rxd->buffer_addr&0x FFFFFFFF);
desc_rbuf[l].len=rxd->length;
l++;

//here the value desc_rbuf[l] is printing right
}

Please post compilable code.

PRINT() is nowhere defined.
fun1 { is a syntax error.
p is nowhere declared.

Regardless, static l; means l equals 0.
for(p = 0; p < l; p++)
That loop is skipped, because 0 < 0 is false.

well this was a same looking code. PRINT is same as printf(); that we
have defined in macro.
problem is not in compilation...
problem is that the PRINT in main(), giving all the values 0 for every
varible fo desc_tbuf[p].everything

there is log file that we take input
u can assign value to the variables in the function ns_nic_desc_inf o &
try to print in main.
any other symbol or function that is not standard 'C' that is d3efined
in our macros
so pls ignore it.
i tried with pointers also but again same problem, whereever u r
allocating the memoty :-(
try something or if u know
pls help me.

I tried that, by inserting the following lines at the beginning of
your program:

#ifdef UNKNOWN
#include "debug.h"
#else
#define uint8_t
#define uint32_t
#define RX
#define PRINT(a, ...)
#define em_rx_desc_t
#define em_tx_desc_t
#define ring_type
#define buf
#define TX
void ns_nic_desc_inf o(uint8_t, char *);
#endif

It didn't help much.

If you want other people to help you, we need complete COMPILABLE
code. For each of those identifiers, give us code that either defines
the identifier, or doesn't use it. You might think you know where
your problem is, and that it doesn't depend upon the things you
haven't given us. However, you came to us for help with a problem that
you couldn't resolve. That means that you don't know what the problem
is, which means that you can't be sure where the problem is. The only
way you can be sure that you've given us enough information, is if you
give us ALL the information.

True, but the person asking for help is the person least likely to be
able to distinguish what is necessary and what is not. Asking them to
send everything removes that possible problem.

Yes. Asking them is one thing. To insist on it for all issues and
questions is, however, a different thing.

Clearly if some one says "my program doesn't work" help then compilable
code is generally necessary.

This was my only point : it is not necessary to have full and complete
code to help someone in probably the majority of cases.

True. If you believe that this is one of those cases, you could prove
that by identifying what the problem is just from the information he's
already given us.

Your problem may well be in the code you chose not to post.

Well, why not point out the other errors too? Does it hurt to do so?
