Abstract:

This library of C functions can be included in your code to simplify the task of manipulating FITS data in either basic FITS format, or Multi-Extension FITS (MEF). Special features of the library are:

• Simple mechanisms to handle FITS with IMAGE and TABLE extensions.
• Novel keyword sorting mechanism using index numbers.
• File locking allows multiple programs to run in parallel on the same file.
• Designed to interface with a status server some time in the future.
