running multiple threads and multiple processes at the same time

[Smegly]

Hi,

I currently trying to implement a simulation banking system as part of an
assigment. I must stress i do not want line by line code to complete this,
what i'm really after is a guide to how i would go about doing this.

I need to read a customer from the file customer_list, into a fifo queue,
every Ts time. (where Ts is expressed in seconds).

Whilst this is happening i also need to have 3 tellers, who when a customer
enters the queues, a free teller grabs the customers and processes there
request, which takes Ts time. (as before). If no customer, teller sleeps.

From thinking about this, I have come up what i believe is the best way to
go.

I think i should create one process that runs the customerInsert() routine,
and then three processes one for each teller ( running the Teller() routine)

Now, the problem that i have is i have never coded in C before. I am quite
well versed in Java, however. Therefore my first question is whats the best
way to start coding this? and secondly, how do i code this ?? Is there C
API DOCS like Java has ??

Thanks in advance,



Matt

What for? I'll just do a big loop, each loop is 1 unit of time
(depending on what your question requires). Every loop I do...

Wait, this is very /Off Topic/ here. Try comp.programming or some
newsgroups concerned with algorithms.

You want threads and stuff, you must look at your platform specific
newsgroups. Standard portable C (which this newsgroup is concerned)
has no API per se, if you mean it the way Java does (drawing buttons,
widgets and all that stuff). Check the C compiler you are using. There
should be some docs.
