Parameter Description
This parameter selects which signaling method is used when a particular MultiCam signal appears.
If an application needs to use one method for signals of a particular type and another method for other signals, it must define this parameter for all concerned signals. If only one signaling method is used for all types of signals, this parameter does not have to be set.
If the setting of SignalHandling :s is CALLBACK_SIGNALING, each signal of type s will cause the callback function to be called. The MultiCam wait function McWaitSignal called for signal s will not be released upon occurrence of a signal of type s. Likewise, the OS event linked to signal s ( SignalEvent :s) will not be signaled.
If the setting of SignalHandling :s is WAITING_SIGNALING, each signal of type s will release the MultiCam wait function McWaitSignal called for signal s. The callback function will not be called upon occurrence of a signal of type s. Likewise, the OS event linked to signal s ( SignalEvent :s) will not be signaled.
If the setting of SignalHandling :s is OS_EVENT_SIGNALING, each signal of type s will cause the corresponding OS event ( SignalEvent :s) to be signaled. The callback function will not be called upon occurrence of a signal of type s. Likewise, the MultiCam wait function McWaitSignal called for signal s will not be released.
