C function woes

hello all:

I am attempting to create a function which will return data from a
C-function. This is what i have, and it so far has been successful. Any
help anyone can give me would be greatly appreciated.

thanks,
chris

{
char data[] = "hello world";
int32 new_text_size = VARHDRSZ + sizeof(data);
text *new_text = (text *) palloc(new_text_size);

strcpy(VARDATA(new_text), data);
return new_text;
}
