| Usage: | PLENGTH = WFDB_wfdbgetstart(SIG_NUM); | |
| Input: | SIG_NUM: signal number (note: the first signal is signal number 0, etc.) | |
| Output: | PLENGTH: prolog length, in bytes |
This function sets the specified prolog length (bytes) to be recorded by WFDB_newheader or WFDB_setheader for signal SIG_NUM. WFDB_wfdbsetstart has no effect on the calculations of byte offsets within signal files as performed by WFDB_isigsettime, which are determined solely by the contents of the '.hea' file at the time the signals were opened.
