Should the data always be received in the order it was sent? If so, try this:
Thanks for your reply..& Sorry If I misguided you..
No its not like that data is not recevied until unless I specify to read exclusively . Think of as a RAM( Read access Memory)
I writes to RAM by specifing TXADDR & TXDATA and I retrives the data when I specify that address with RXADDR , I get RXDATA ie, last written on that addresss.
Actually Wrrtting and reading are independent of each other.
Once I give TXADDR & TXDATA (5 burst - In INPUT FILE you can see five lines of input data contineously). Then after that I am going to Read those values when RXADDR comes ..
Suppose I am writting to the same address twice then reading from that address then it ll read the lastest value that is written to that address.
Thanks

Hello friends,
I have a problem in printing an array..
Example if my array line contains 4 elements like following
line=0002 , line=202200, line=200002, line= 300313
Now one = sprintf line line line line will concatenate my whole array to one.

bcopy
bcopy(9F) Kernel Functions for Drivers bcopy(9F)NAME
bcopy - copy data between address locations in the kernel
SYNOPSIS
#include <sys/types.h>
#include <sys/sunddi.h>
void bcopy(const void *from, void *to, size_t bcount);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
from Source address from which the copy is made.
to Destination address to which copy is made.
bcount The number of bytes moved.
DESCRIPTION
bcopy() copies bcount bytes from one kernel address to another. If the input and output addresses overlap, the command executes, but the
results may not be as expected.
Note that bcopy() should never be used to move data in or out of a user buffer, because it has no provision for handling page faults. The
user address space can be swapped out at any time, and bcopy() always assumes that there will be no paging faults. If bcopy() attempts to
access the user buffer when it is swapped out, the system will panic. It is safe to use bcopy() to move data within kernel space, since
kernel space is never swapped out.
CONTEXT
bcopy() can be called from user or interrupt context.
EXAMPLES
Example 1: Copying data between address locations in the kernel:
An I/O request is made for data stored in a RAM disk. If the I/O operation is a read request, the data is copied from the RAM disk to a
buffer (line 8). If it is a write request, the data is copied from a buffer to the RAM disk (line 15). bcopy() is used since both the RAM
disk and the buffer are part of the kernel address space.
1 #define RAMDNBLK 1000 /* blocks in the RAM disk */
2 #define RAMDBSIZ 512 /* bytes per block */
3 char ramdblks[RAMDNBLK][RAMDBSIZ]; /* blocks forming RAM
/* disk
...
4
5 if (bp->b_flags & B_READ) /* if read request, copy data */
6 /* from RAM disk data block */
7 /* to system buffer */
8 bcopy(&ramdblks[bp->b_blkno][0], bp->b_un.b_addr,
9 bp->b_bcount);
10
11 else /* else write request, */
12 /* copy data from a */
13 /* system buffer to RAM disk */
14 /* data block */
15 bcopy(bp->b_un.b_addr, &ramdblks[bp->b_blkno][0],
16 bp->b_bcount);

WARNINGS
The from and to addresses must be within the kernel space. No range checking is done. If an address outside of the kernel space is
selected, the driver may corrupt the system in an unpredictable way.
