Hi,
Can i pass a parameter(not a file name) as a parameter to a awk program?
eg;
$awk -f test 1 2 3
here test is the filename...and 1,2,3 are the i/p parameters?
thank you:-) (2 Replies)
I have something like
cp -p <dir>filename1.dat <dir2>filename1.dat
there are many other operations in it
I mean that filename1.dat will keep on changing
I need to write a subroutine so that i can pass filename1 or 2 or 3 .dat as parameter
Thanking you in advance
Any help wuld be appreciated (2 Replies)

fec
FEC(3) BSD Library Functions Manual FEC(3)NAME
fec_new, fec_encode, fec_encode, fec_free -- An erasure code in GF(2^m)
SYNOPSIS
#include <fec.h>
void *
fec_new(int k, int n);
void
fec_encode(void *code, void *data[], void *dst, int i, int sz);
int
fec_decode(void *code, void *data[], int i[], int sz);
void *
fec_free(void *code);
DESCRIPTION
This library implements a simple (n,k) erasure code based on Vandermonde matrices. The encoder takes k packets of size sz each, and is able
to produce up to n different encoded packets, numbered from 0 to n-1, such that any subset of k of them permits reconstruction of the origi-
nal data.
The data structures necessary for the encoding/decoding must first be created using calling fec_new() with the desired parameters. The code
descriptor returned by the function must be passed to other functions, and destroyed calling fec_free()
Allowed values for k and n depend on a compile-time value of GF_BITS and must be k <= n <= 2^GF_BITS. Best performance is achieved with
GF_BITS=8, although the code supports also GF_BITS=16.
Encoding is done by calling fec_encode() and passing it pointers to the code descriptor, the source and destination data packets, the index
of the packet to be produced, and the size of the packet.
fec_decode() with pointers to the code, received packets, indexes of received packets, and packet size. Decoding is done in place, possibly
shuffling the arrays passed as parameters. Decoding is deterministic as long as the received packets are different. The decoding procedure
does some limited testing on this and returns if parameters are invalid.
EXAMPLE
#include <fec.h>
/*
* example of sender code
*/
void *code ;
int n, k ;
void *src[] ;
void *pkt ;
code = new_code (k, n );
for (i = 0 ; i < k ; i++ )
src[i] = .. pointer to i-th source packet ..
for (each packet to transmit) {
i = ... index of the packet ;
fec_encode(code, src, pkt, i, size) ;
.. use packet in pkt
}
fec_free(code) ;
/*
* example of receiver code
*/
void *code ;
int n, k ;
void *data[] ;
int *ix[] ;
code = new_code (k, n );
for (i = 0 ; i < k ; i++ ) {
... receive a new packet ...
data[i] = .. pointer to i-th source packet ..
ix[i] = .. index of i-th source packet ..
}
fec_decode(code, data, ix, size) ;
/*
* now data[] has pointers to the source packets
*/
