116723 Document Conversion using C

A program written in C to convert different file types to 1D Group 3 T4 The program will need to take a document supplied to it on a command line (Linux / UNIX) with parameters to convert any of the following document types to the file type above. The program will have to read the original document file headers to determine what the file is so that it can convert it. It will also need to cope with multiple pages within the file and save them out with an increasing file extension number, for instance a 1 page document would be .001 or .002 (if instructed to start at .002 (see below), a 5 page document would be .001, .002, .003, .004, .005 again if instructed to do so via command line it might start at .002 through to .006 , As we don't know the end page number it will continue until it finishes the whole original document. The original document filename of [login to view URL] will once conversion has taken place be testtest.001 (or .002 if instructed to do so on command line) Command line switches need to be available, the main 2 are : 1. Filename of original document to convert Our program will tell the conversion program where and what the file is called 2. File extension number to start on. Our program will tell the conversion program what number to start the saved file extension with either .001, .002, .003 etc On successful conversion program should write the number of pages converted (in ascii) to the standard output and return with a zero exit code, otherwise it should return a non zero exit code for a failure. All source code will need to be supplied so that we can compile it on our own platforms. This list is a complete list, if you can only do some of them, please PMB to tell us which ones you can do within your conversion program.
