I will assume you want to change the header but keep the rest of the 30 million lines. Since the new header has the same length, the following will open file for both reading and writing:
This will be very fast and replace the file in place. Be careful.
Hello,
Does changing a header in a shared library under Solaris (say adding a new class data member) will result in not only compiling that library but all of the libraries that depend on that lib that was changed because of the change in the object's size? What about adding a virtual function?... (0 Replies)

cgisetheader
cgiSetHeader(3) Programmer's Manual cgiSetHeader(3)NAME
cgiSetHeader - Specify an additional HTTP header
SYNOPSYS
#include <cgi.h>
int cgiSetHeader (char *name, char *value);
DESCRIPTION
With the cgiSetHeader routine you may specify additional HTTP header lines such as Expires: or Pragma:. The order of header lines withing
the HTTP header has no significance. You may call this routine multiple times to set multiple headers. They will be printed in the same
order as specified, however, after the Content-type: header.
This routine will only add the header to the internal stack, not print it. They will be printed by cgiHeader(3).
This routine does some syntax checking before accepting a new header. The name of a header must not contain any newline, space or colon,
otherwise it will be truncated. The value must not contain any newline, otherwise it will be truncated as well.
To set a cookie in your program you'll need to manually add additional header lines. Please take a look at cgitest.c. Basically, you'll
need to add the following code:
cgiSetHeader ("Set-Cookie", "Version=1; name=value; Path=/");
cgiHeader();
Please read the included file cookies.txt as well.
RETURN VALUE
On success 1 is returned, otherwise 0.
