WFDB_wfdbsetstart

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.
