Description

Type	Enumerated collection
Description	Selection of signaling method to use when MultiCam signal appears
"Set" effect	Sets a particular signaling method
"Get" effect	Returns the current signaling method

Classification

Class	Channel
Category	Signaling
Level	Expert

Identifiers

String	SignalHandling
C, C++	MC_SignalHandling
.NET	MC.SignalHandling
Numerical	74

This collection 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.

Possible values

Name	Identifier	Description
ANY	MC_SignalHandling_ANY	No signaling method has been selected.
CALLBACK_SIGNALING	MC_SignalHandling_CALLBACK_SIGNALING	The callback signaling method is used.
WAITING_SIGNALING	MC_SignalHandling_WAITING_SIGNALING	The waiting signaling method is used.
OS_EVENT_SIGNALING	MC_SignalHandling_OS_EVENT_SIGNALING	The OS event signaling method is used.
