generating autoincrement value

[reshmaah]

hi
iam interested in generating a variable value by autoincrementing, in CGI using c

as user enters some data, i want to generate an index for it,
and store in a binary file with data,
as we create a field in mysql with autoincrement.

I'm kind of confused as to what your question is. Are you wanting to count the number of times a user enters data? In that case you'd just do this

int cnt = 0;
//User enters data
cnt++;

from front end(HTML PAGE) if user enters data, i want to store with data the index, in to a binary file
so this index should increment next time another request comes in CGI c program.
as we do in anydata base

The recommended approach is to use a Singleton to manage the count. (See the Singleton article in the C/C++ Articles forum).

You could also use a local static variable for the count but a) this approach is deprecated in C++, and b) is not thread-safe so you can't do this on multiple threads.
