Result is a variable that contains a value indicating the success or failure of the command. A
result code of 0 means the command was successful. If reading a setting, 0 in the result code
means that the value in the
DestSource
variable is the value the desired setting has in the
IRGASON. When writing a setting, if the result code is 0, the value and setting were compatible,
but the value was not changed because it contained the same value that was sent. A result code
of 1 from the set operation means that the value was valid, different, set and acknowledged. This
allows CRBasic code to control whether or not to save the settings. A result code of NAN (not a
number) indicates the setting was not changed or acknowledged, or a signature failure occurred.
SDMAddress defines the address of the IRGASON to configure. Valid SDM addresses are 0
through 14 (address 15 is reserved for
SDMTrigger()
).
ConfigCmd
is a variable that indicates whether to get or set a setting. The options are listed in
Table 10-4 (p. 50).
DestSource
is a variable that will contain the value to read when getting a setting, or that will
contain the value to send when writing a setting to the IRGASON.
