I seem to misunderstand a basic syntax, why this sample works: sqlite3_prepare_v2(db, "insert into test values('boo','boo',0);", strlen(querystring)+1 , &stmt, NULL); if ((rc = sqlite3_step(stmt)) != SQLITE_DONE) fprintf(stderr, "Error: sqlite3_step() %d. Error Message %s;\n",rc,sqlite3_errmsg(db)); But when I try this query: "inse...
Hello, I am trying to set up a list of file names for a parameter to SHFileOperation. I want to be able to concatenate a file name onto the char array, but i dont want to get rid of the terminating character. for example, I want this: C:\...\0E:\...\0F:\...\0\0 when i use strcat(), it overwrites the null, so it looks like C:\...E:\......
I'm using the algorithm below to generate quads which are then rendered to make an outline like this http://img810.imageshack.us/img810/8530/uhohz.png The problem as seen on the image, is that sometimes the lines are too thin when they should always be the same width. My algorithm finds the 4 verticies for the first one then the t...
Hello We are working on a C language application which is simple RTSP/RTP client to record video from Axis a number of Cameras . We launch a pthread for each of the camera which establishes the RTP session and begins to record the packets captured suing the recvfrom() call... A single camera single pthread records fine for well over a d...
Hi, I was trying to write a small debug utility and for this I need to get the function/global variable address given its name. This is built-in debug utility, which means that the debug utility will run from within the code to be debugged or in plain words I cannot parse the executable file. Now is there a well-known way to do that ? ...

I have done far more C++ programming than "plain old C" programming. One thing I sorely miss when programming in plain C is type-safe generic data structures, which are provided in C++ via templates. For sake of concreteness, consider a generic singly linked list. In C++, it is a simple matter to define your own template class, and th...

My program uses sockets, what Parallel computing APIs could I use that would help me without obligating me to go from sockets to anything else? When we are on a cluster with a special, non-socket infrastructure system this API would emulate something like sockets but using that infrastructure (so programs perform much faster than on soc...
I'm using and x86 based core to manipulate a 32-bit memory mapped register. My hardware behaves correctly only if the CPU generates 32-bit wide reads and writes to this register. The register is aligned on a 32-bit address and is not addressable at byte granularity. What can I do to guarantee that my C (or C99) compiler will only gene...
Hi! I'm totally new in C, and I'm trying to do a little application that searches a string into a file, my problem is that I need to open a big file (more than 1GB) with just one line inside and fgets return me the entire file (I'm doing test with a 10KB file). actually this is my code: #include <stdio.h> #include <string.h> int mai...
It seems to be an 'accepted concept' in the popular culture of programming languages that 'C is portable assembler'. I have first heard this at least 15 years ago. But when did it really become part of the popular culture? Note: if you don't agree that 'C is portable assembler', please just skip this question. This question is about ...
I am trying to identify a method for obtaining nearby wifi access points using C in Windows. I am coding in Visual Studio 2010. I have read the necessary documentation but am lacking in guidance on how to implement code that would accomplish this. I am specifically interested in obtaining the MAC address of nearby access points or at a ...

I have a project for Linux that i've been developing for some time. Basically it's a bunch of C and H files together with a directory structure and a Makefile. Every time I need to debug something it's so painful, I need to manually search for var. definitions, structs, etc. Is there any good IDE out there for Linux that will allow me ...
I'm implementing an FTP-like protocol in Linux kernel 2.4 (homework), and I was under the impression that if a file is open for writing any subsequent attempt to open it by another thread should fail, until I actually tried it and discovered it goes through. How do I prevent this from happening? PS: I'm using open() to open the file....
Is there a way to draw many filled circles using one vertex array. Is there a way to draw a circle with triangles? I basically have hundreds of circles far apart from each other that need to be drawn but I feeling calling the vertex pointer for each circle is inefficient. I'd rather make 1 call for all circles if possible. Thanks ...
I'm in linker paradise now. I have a C library which only compiles in Visual C++ (it probably works in gcc) if: I compile it as C++ code Define __cplusplus which results in all the declarations being enclosed in extern "C" { } So, by doing this I have a static library called, say, bsbs.lib Now, I have a C++ project called Tester whi...
I'm Working in an embedded linux environment. it launches a telnet daemon on startup which watches on a particular port and launches a program when a connection is received. i.e. telnetd -l /usr/local/bin/PROGA -p 1234 PROGA - will output some data at irregular intervals. When it is not outputting data, every X period of time it se...
I'm using OpenGL and was told I should draw circles at each vertex of my outline to get smoothness. I tried this and it works great. The problem is speed. It crippled my application to draw a circle at each vertex. I'm not sure how else to fix the anomaly of my outlines other than circles, but using display lists and trying with vertex a...
