- Module Name:
-
- DscFile.c
-
- Abstract:
-
- This module is used to process description files at a high level. For the
- most part, it pre-parses the file to find and save off positions of all
- the sections ([section.subsection.subsection]) in a linked list, then
- provides services to find the sections by name, and read the lines from
- the section until you run into the next section.
-
- NOTE: DSC file is synonomous with section file. A DSC file is simply a file
- containing bracketed section names [section.subsection.subsection...]

-Routine Description:
-
- Pre-scan a section file to find all the sections. Then we can speed up
- searching for the different sections.
-
-Arguments:
-
- DSC - pointer to a DSC structure (this pointer)
- FileName - name of the file to process
-
-Returns:
-
- STATUS_SUCCESS if everything went well.
