Hi,
Almost a year ago I was looking at adding skel dir capability to
vpopmail (check the archives - 23/11/04 !).
For one reason or another I never quite got round to it.
However, tonight I've started putting something together.
The thing is, I've not done much programming in C before. Pascal, sure.
Perl - I'm a wizard :)
So, I've put together a section of code, which may or may not be valid
C, and would appreciate comments.
Introduction
============
This code is intended to add skel dir functionality to vpopmail.
It first looks for a domain-specific skel dir in:
/home/vpopmail/etc/domains/<domain>/skel
It then looks for a installation-specific skel dir in;
/home/vpopmail/etc/skel
If neither are found, it creates the default maildir structure.
===== snippet of vpopmail.c ==========
/* Initialise a couple of strings to hold directory paths
char skel_dir[MAX_BUFF];
char skel_location[MAX_BUFF];
/* initialise skel dir to empty */
strcpy(skel_dir,"");
/* first directory to check */
snprintf(skel_location, sizeof(skel_location),
"%s/etc/domains/%s/skel",
VPOPMAILDIR, domain);
/* check if it exists + is readable */
if (check_dir_readable(skel_location)) {
/* set the skel dir */
snprintf(skel_dir, sizeof(skel_dir), "%s", skel_location)
} else {
/* next directory to check */
snprintf(skel_location, sizeof(skel_location),
"%s/etc/skel",
VPOPMAILDIR);
/* check if it exists + is readable */
if (check_dir_readable(skel_location)) {
/* set the skel dir */
snprintf(skel_dir, sizeof(skel_dir), "%s", skel_location);
}
};
/* if one of the skel dirs exists, use it */
if (skel_dir <> "") {
/* copy it to the newly-created user dir */
copydir(skel_dir, ".");
} else {
/* otherwise, create the default dir structure */
/* (this is core vpopmail code) */
for (i = 0; i < sizeof(dirnames)/sizeof(dirnames[0]); i++) {
if (mkdir(dirnames[i],VPOPMAIL_DIR_MODE) == -1){
fprintf(stderr, "make_user_dir: failed on %s\n", dirnames[i]);
/* back out of changes made above */
chdir("..");
vdelfiles(username);
chdir(calling_dir);
return(NULL);
}
}
}
===== snippet of vpopmail.c ==========
I've not yet written the check_dir_readable() or copydir() functions;
check_dir_readable may be really easy (it is in Perl :) ) but I've not
looked into how to implement it. copydir() is probably already available
somewhere if I have a quick google.
I'd appreciate any comments before I go any further with this.
Thanks,
R.
