ATDX_FRQDUR( )

Description | Cautions | Example | See Also

Name:	long ATDX_FRQDUR(chdev)
Inputs:	int chdev	valid Dialogic channel device handle
Returns:	first frequency duration in 10ms units AT_FAILURE if error
Includes:	srllib.h dxxxlib.h
Category:	Extended Attribute

Description

The ATDX_FRQDUR( ) function returns the duration of the first SIT tone in 10 ms units after dx_dial( ) terminated due to an Operator Intercept.

Termination due to Operator Intercept is indicated by ATDX_CPTERM( ) returning CR_CEPT.

The function parameter is defined as follows:

Parameter	Description
chdev	specifies the valid channel device handle obtained when the channel was opened using dx_open( ).

Cautions

None.
