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?

NAME
mech, qop - security mechanism and quality of protection (QOP) files SYNOPSIS
DESCRIPTION
The and files contain tables showing installed security mechanisms and the Quality of Protection (QOP) associated with them, respectively. These files are accessed by GSS-API calls; see gssapi(5). As security mechanisms are installed on the system, entries are added to these two files. Contents of these files may be accessed either manually or programmatically; for example, manually with cat(1) or more(1), or programmati- cally with either rpc_gss_get_mechanisms(3N) or rpc_gss_get_mech_info(3N). /etc/gss/mech The file contains these fields: mechanism name ASCII string representing the mechanism. object identifier OID for this mechanism. shared library Shared library which implements the services provided by this mechanism. kernel module Kernel module which implements the services provided by this mechanism. /etc/gss/qop The file contains these fields: QOP string Name, in ASCII, of this Quality of Protection. QOP value Numeric value by which QOP can be identified. mechanism name ASCII string representing the mechanism with which this QOP is associated. EXAMPLES
