use chmod() in C

[datct0407]

I want to use function chmod() to remove all attribution of a file in C, but i don't know how!
Can you help me!

I don't know if this is what you're looking for, but you can use the system() function to have a C program execute a command.

for example, I have a file as SYSTEM.INI, its attributions are HIDDEN, ARCHIVE, READ ONLY. And I want to remove all attribution it has.
Do you understand??? Help me!

In most (if not all) unices there's the chmod(2) function:

#include <sys/types.h>
#include <sys/stat.h> 
int chmod(const char *path, mode_t mode);
 

For windows I vaguely remember a 'cacls' method; check it out.

kind regards,

Yes or you could use SetFileAttributes. You would be well advised to call GetFileAttributes first though and only change what you want.

maybe You don't understand my question!
I want to remove all attributions, not set attributions!
ok??
