| Usage: | S = WFDB_osigopen(RECORD, NSIG); | |
| Input: | RECORD: (string) record name | |
| NSIG: number of signals to open | ||
| Output: | S: Siginfo structure(s) |
This function opens output signal files. Use it only if signals are to be written using WFDB_putvec. The signal specifications, including the file names, are read from the header file for a specified record and returned in the structure array S. If RECORD begins with `+', previously opened output signal files are left open, and the record name is taken to be the remainder of RECORD after discarding the `+'. Otherwise, osigopen closes any previously opened output signal files, and takes all of RECORD as the record name. S is a WFDB_Siginfo structure array which, on return, will be filled with the signal specifications.
No more than NSIG (additional) output signals will be opened by WFDB_osigopen, even if the header file contains specifications for more than NSIG signals.
