Kernel programming sys_creat

Hi there

At first.
My Name is Andre, 27 and im from germany

Im tryin to learn something about the Unix Kernel and System

At first im trying to manipulate the systemcalls

I want to have an Entry in the kernel logfile, whenever a new file is created.

I found out, that a file uses the sys_creat function, to be created.
This function is referencing to the sys_open

But here is the point, where i dont get any further..

Where exactly can i find this function?

I hope that my english is good enough, that you can understand my problem Smilie

Andre

edit: It seems, that the function can be foun in fs/open.c?
line: 927
if (flags & O_CREAT) {
op->intent |= LOOKUP_CREATE;

i guess, here we have the point?
can someone explain that to me?

get_config_text(3alleg4)					  Allegro manual					  get_config_text(3alleg4)

NAME
get_config_text - Returns a string translated to the current language. Allegro game programming library. SYNOPSIS
#include <allegro.h> const char *get_config_text(const char *msg); DESCRIPTION
This function is primarily intended for use by internal library code, but it may perhaps be helpful to application programmers as well. It uses the `language.dat' or `XXtext.cfg' files (where XX is a language code) to look up a translated version of the parameter in the cur- rently selected language. This is basically the same thing as calling get_config_string() with `[language]' as the section, `msg' as the variable name, and `msg' as the default value, but it contains some special code to handle Unicode format conversions. The `msg' parameter is always given in ASCII format, but the returned string will be converted into the current text encoding, with memory being allocated as required, so you can assume that this pointer will persist without having to manually allocate storage space for each string. Note that if you are planning on distributing your game on the Unix platform there is a special issue with how to deal with the `lan- guage.dat' file. Read section "Files shared by Allegro" of the chapter "Unix specifics" to learn more about this. RETURN VALUE
Returns a suitable translation if one can be found or a copy of the parameter if nothing else is available. SEE ALSO
