The cal argument for getcal
and putcal
is a pointer
to an object of type WFDB_Calinfo
. A WFDB_Calinfo
object
contains information about signals of a specified type:
char *sigtype
sigtype
is an exact match to
(or a prefix of) the desc
field of the WFDB_Siginfo
object
that describes a matching signal.
char *units
units
field of
a WFDB_Calinfo
structure must exactly match the units
field of
the WFDB_Siginfo
structure that describes a matching signal.
double scale
scale
as a
default. Except in unusual circumstances, signals of different types
should be plotted at equal multiples of their respective scale
s.
double low
double high
low
is zero, and high
is the pulse amplitude.
int caltype
caltype
is even if signals of
the corresponding sigtype
are AC-coupled, and odd if they are
DC-coupled.
The calibration list is a memory-resident linked list of WFDB_Calinfo
structures. It is accessible only via calopen
, getcal
,
putcal
, newcal
, and flushcal
.
