last question... i promise. :)
Hi,
i understand what you say about the while(1), sleep(1), someone had actually told me to put it in on another forum(which wasn't that helpfull at all),
but my question is about the fork, when you said i need to fork in the begining, do you mean all the forking is done in the main(), and it just calls the function from there?(instead of forking in the List())
.... i was thinking of putting
for(;
{ open directory, and do all the file stuff here}, but that isn't working either.
I'm sorry to bugg you with this... i think i'm just having problems with the logic here. like you said it goes into infinate sleep.... so i though an infinite loop would help. but is it in the wrong place?
thanks again
Tanya R.

qmail-start
qmail-start(8) System Manager's Manual qmail-start(8) NAME
qmail-start - turn on mail delivery SYNOPSIS
qmail-start [ defaultdelivery [ logger arg ... ] ] DESCRIPTION
qmail-start invokes qmail-send, qmail-lspawn, qmail-rspawn, and qmail-clean, under the proper uids and gids. These four daemons cooperate to deliver messages from the queue. qmail-start arranges for qmail-send's activity record to be sent to qmail-start's output. See qmail-log(5) for the format of the activity record. Other than this, qmail-start does not print anything, even on failure. If defaultdelivery is supplied, qmail-start passes it to qmail-lspawn. If logger is supplied, qmail-start invokes logger with the given arguments, and feeds qmail-send's activity record through logger. Environment variables given to qmail-start will eventually be passed on to qmail-local, so make sure to clean up the environment if you run qmail-start manually: # env - PATH="/var/lib/qmail/bin:$PATH" qmail-start ./Mailbox splogger qmail & (all on one line) Resource limits, controlling ttys, et al. are also passed from qmail-start to qmail-local. Note that qmail-send normally juggles several simultaneous deliveries. To reduce qmail-send's impact on other programs, you can run qmail- start with a low priority. SEE ALSO
