LINEMEDIACONTROLDIGIT

The LINEMEDIACONTROLDIGIT structure describes a media action to be executed when detecting a digit. It is used as an entry in an array. The lineSetMediaControl and TSPI_lineSetMediaControl functions use this structure.

typedef struct linemediacontroldigit_tag {
  DWORD  dwDigit;
  DWORD  dwDigitModes;
  DWORD  dwMediaControl;
} LINEMEDIACONTROLDIGIT, FAR *LPLINEMEDIACONTROLDIGIT; 

Members

dwDigit

The low-order byte of this DWORD specifies the digit in whose detection is to trigger a media action. Valid digits depend on the media type.

dwDigitModes

The digit mode(s) to monitor. This member uses one or more of the LINEDIGITMODE_ Constants.

dwMediaControl

The media control action. This member uses one of the LINEMEDIACONTROL_ Constants.

Remarks

This structure may not be extended.

The LINEMEDIACONTROLMEDIA structure defines a triple <digit, digit mode(s), media-control action>. An array of these triples is passed to the lineSetMediaControl function to set the media control actions triggered by digits detected on a given call. When a listed digit is detected, then the corresponding action on the media stream is invoked.
