Task: Application written in Delphi accepts a structure (record in terms of Delphi) of three fields. I can send the pointer of this structure using SendMessage (Win32api) function. So a question is: How to maintain certain structure representation in memory for delphi in terms of delphi. It has type PWPModPostData = ^ TWPModPostDat...
Okay this is my code for deleting a node from a linked list. vec_store holds seq and size. Variable seq holds the vectors and a pointer. For some reason, the else if(i<s->size-1) doesn't work which is the last condition. Any1 can solve the problem? By the way this is C code. void delete_vec(vec_store s, int i) { if (i<0 || s->si...
I'm working on a mobile phone application and I see a potential opportunity for performance improvement. Throughout the code I use bool arrays to keep track of which objects are active. For example I'd check to see if the ith MyObject is active by doing the following: if(activeMyObjects[i]){ // it's active so do something... } Since...
Hi, Could someone please help me with synchronizing varied number of threads? The problem is when the number of threads can vary from one to 9 and when for instance two clients are connected to server, the communication should be synchronized in this form : client1, client2, client1, client2 ... until the communication is over. I tried ...
I am trying to send my struct over a UDP socket. struct Packet { int seqnum; char data[BUFFERSIZE]; }; So on the sender I have bytes = sizeof(packet); char sending[bytes]; bzero(sending, bytes); memcpy((void *) sending, (void *) &packet, sizeof(bytes)); bytes = sendto(sockfd, sending, sizeof(sending), 0, (struct sockaddr *...
Playing around with this a bit, but not getting too far... The logic of my SQLite code works if I compile it as a stand-alone executable. My mod_hello.c compiles and loads/works fine without the SQLite code Combining the two, the module compiles and is installed, but the apache process dies immediately every time it is loaded.

I have a C code in which I do the following int nPosVal = +0xFFFF; // + Added for ease of understanding int nNegVal = -0xFFFF; // - Added for valid reason Now when I try the following printf ("%d %d", nPosVal >> 1, nNegVal >> 1); I get 32767 -32768 Q-1: Is this expected? I am able to think something like 65535 >> 1 = (int)...
I'm writing a socket program that maintains FIFO queues for two input sockets. When deciding which queue to service, the program pulls the most recent time-stamp from each queue. I need a reliable method for comparing two timeval structs. I tried using timercmp(), but my version of gcc doesn't support it, and documentation states that ...
