Hi experts, I'm doing a OpenSSL project and I'm completely new to web server. I've got a client.c and server.c. client.c creates a connection to the server on port 6008 and reads data from stdin and then send those data to the server. The server.c reads data from socket and writes it back out to stdout. I've got the server.c compiled o...
I've tried this on Linux and Windows... I've used C and C++... I've tried with wxWidgets, gtkmm, glfw and GTK+. I've tried with various IDE's and so on.

In C programming, is there any way to determine how much a single source code file contributes to the final memory footprint? Let us assume a simple C-program consisting of source files test1.c, test2.c, test3.c, and so on. The environment is Linux and the complier gcc.

The counter in the for loop is a pointer that points to the beginning of a primitive array, it increments itself till it finds a "terminator number". The array pointed is used to build a view, each elements represent a subview to put in the ...
When we talk about dereference, is it necessary that * should be used in it? If we access the referent of the pointer in some other way, can it be considered as dereferencing a pointer or not, like: char *ptr = "abc" ; printf( "%c" , *ptr ); // Here pointer is dereferenced. printf( "%s" , ptr ); // What about this one? That is the f...
I have difficulty in understanding the use of union in C. I have read lot of posts here on SO about the subject. But none of them explains about why union is preferred when same thing can be achieved using a struct. Quoting from K&R As an example such as might be found in a compiler symbol table manager, suppose that a constant...
