problem in sed script

[Anand_30]

I have a sed script which I am using to change some lines in the program generated by rpcgen.
I want to change
(void) svc_sendreply(transp, xdr_void,
(char *)NULL);

to

(void) svc_sendreply(transp, (xdrproc_t)xdr_void,(char *)NULL);

How do I specify this in the sed script.
I have tried:

s/(void) svc_sendreply(transp, xdr_void,(char *)NULL) {/(void) svc_sendreply(tr
ansp, (xdrproc_t)xdr_void,(char *)NULL){/1

But not getting the desired result. Any help will be highly appreciated.

first i'd try escaping special characters with a backslash, i.e. instead of *, use \*

Anand -
To add to Curt's response, I have found the need at times to single quote between eacho of the / / / i.e. s/'xyz'/'abc'/
another as suggested

s/\^M/'KO'/

Best of luck.
