Programming

I don't think you've solve the underlying problem. I see no reason to re-declare pcName as you have.

When you overwrite a data structure (heap, stack, etc.), there will be trouble. Increasing the buffer size, moving it into another data storage area, or other finagling simply delays or relocates the trouble. Be sure to understand your data size limitations, and ensure your program never exceeds their bounds. Any other solution is broken by definition.

It sounds like you are unsure of the exact number of bytes used by your data structures. Now might be a good time to sit down with pencil and paper and start drawing some size diagrams, complete with starting and ending virtual addresses for those data structures. This will help you see what you may be overwriting.

Thanks for advice its really useful.... I understood it in full. I might analyze what i have written in pen & paper. By the way, i changed the coding style. Check out the edited version of the post. I know the program is not efficient, but this is my first network programming, so all i need is to get my had dirty. Your advice will help me in the long run

Looks better. It's far more complicated that it needs to be with all the conversion back and forth between the various string and char * types.

Try: man sprintf

btw. my description of strcpy and strcat was backwards. I don't know where my head was at. strcpy is what you want; strcat is for appending existing strings. Sorry for the noise.

lol...its alright! i realized it anyway. Your help is appreciated m8!
