A calender filter and updater program using Pthreads
Advanced Systems Programming: Assignment 2
Problem Statement
The program has been divided in several source files. The description is as follows:
calenderUpdater.c : Main function resides here. This is the main app.
producerConsumer.c : Has two thread functions "producerThread" (emailFilter) & "consumerThread" (calenderFilter), producer is atomically writing to and consumer is atomically reading from circularBuffer, managed by manageBuffer.c.
manageBuffer.c : Has function for creating a dynamic circular buffer and to destroy it.
emailFilter.c : Functions associated with checking the valid email formats and producing filtered email output.
calenderFilter.c : Functions associated with dynamically updating the calender events in order that they are produced from emailFilter (producerThread) from the circularBuffer.
stringPool.c : Functions associated with managing a pool of events, it maintains a global pool of all the events. It maintains a structure stringPool_t which has date entries of all the dates, and a linked list for each such entries in the pool. All the events are stored in a "time" sorted order in these lists.
eventProcessing.c : Basic functions to compare events, check which one is earlier in time, get the latest event of the day etc.
eventList.c : Functions required for linked list: sortedInsert, deleting events, adding or updating events, creating and/or destroying linked lists.
stringProcessing.c : Functions for parsing the given input email into events, and other string manipulating functions.
