Hello, c program compiler gcc I have 3 files. main.c stop_watch.h and stop_watch.c This program does work. I call start_stopwatch. And it will callback in main.c timeout_cb() after the time has expired. I also run this in a seperate thread, as I don't want to block in main, as I will have other code I need to run. 1) The seconds in g...

Hi I haven't been writing C for very long, and so I'm not sure about how I should go about doing these sorts of recursive things... I would like each cell to contain another cell, but I get an error along the lines of "field 'child' has incomplete type". What's up? typedef struct Cell { int isParent; Cell child; } Cell; Thanks, ...
I am having growing pains moving from Java to C. I have become used to having different methods with the same name, but which take different parameters. In C this creates problems? Cell makeCell(int dim, int iterations, Cell parent); Cell makeCell(Cell parent); Is there some quick little work around for this problem, or should I just...

I am using Stackdumps with Win32, to write all return adresses into my logfile. I match these with a mapfile later on (see my article [Post Mortem Debugging][1]). EDIT:: Problem solved - see my own answer below. With Windows x64 i do not find a reliable way to write only the return adresses into the logfile. I tried several ways: Tri...

hello, i'm looking at a core from a process running in Unix. Usually I can work my around and root into the backtrace to try identify a memory issue. In this case, I'm not sure how to proceed.

I can call an ORACLE stored procedure through OCI in a C program by constructing the SQL command for the command, here's a brief snippet from my code: /* build sql statement calling stored procedure */ strcpy ( sql_stmt, "call get_tab_info(:x)" ); rc = OCIStmtPrepare(p_sql, p_err, sql_stmt, (ub4) strlen (sql_...
Generally I would go about this by placing something(s) unique and random in the ROM image and use that as a seed to encrypt the EEPROM content to stop extraction and reprogram after image mod. An obvious flaw seems to be that this doesn't stop tampering in the form of replacing the EEPROM external chip with a blank one... oh look were ...

Unit selection on P5, according to the unit selected output value is calculated and displayed on LCD. now a unit "IN WC" is showing binary averaged vale of inp...
I realize "fast" is a bit subjective so I'll explain with some context. I'm working on a Python module called psutil for reading process information in a cross-platform way. One of the functions is a pid_exists(pid) function for determining if a PID is in the current process list. Right now I'm doing this the obvious way, using EnumProc...
For a web project I need the possibility to generate jpg and animated gif images very fast. As server platform I will use Linux and the NekoVM (behind a apache via mod_tora). As there is no library for image generation for haXe and neko I am about to write a own one. Neko itself is written in c, and you can simply extend the VM writing ...
