[aclug-L] C questions

[Olwe Bottorff <galanolwe@xxxxxxxxx>]

I'm trying to create a directory in C where I use

mkdir(const char *pathname, mode_t mode);

I'd like to take a simple string "0775" and somehow
use that for the mode argument. I'm getting the
permissions as a char string from a file. Now, if you
do this:

mkdir ("mydir", 0755); /* 0755 directly typed in */

It works fine. But I can't figure out how to get a
variable (char or otherwise) with 0755 in it that
mkdir will accept. Of course I could parse each letter
and build the variable, but that just isn't very
elegant.

I'm also trying this for utime(), i.e., trying to feed
the utimbuf argument to utime from a string I'm
getting from a file.
