Header Files

Header files have names of the form `record.hea', where record is the record name. (MIT DB records are named 100--124 and 200--234 with some numbers missing. AHA DB records are named 1001--1010, 2001--2010, 3001--3010, 4001--4010, 5001--5010, 6001--6010, 7001--7010, and 8001--8010. ESC DB records are named e0103--e1304, with many numbers missing.) Header files are text files, with lines terminated by ASCII carriage-return/line-feed pairs, created by newheader, setheader, or setmsheader, from which isigopen, osigopen, and wfdbinit read the names of the signal files and their attributes as given in the array of WFDB_Siginfo objects; sampfreq also reads a header file to determine the sampling frequency used for a record.
