record voice data to a single file — dx_recf( )
dx_recf( )
record voice data to a single file
!
!!
! Description
The dx_recf( ) function is a convenience function that records voice data from a channel to a single
file.
Calling dx_recf( ) is the same as calling dx_rec( ) and specifying a single file entry in the
DX_IOTT structure. Using dx_recf( ) is more convenient for recording to one file, because you do
not have to set up a DX_IOTT structure for one file, and the application does not need to open the
file. The dx_recf( ) function opens and closes the file specified by fnamep.

None.

Parameter Description
chdev specifies the valid channel device handle obtained when the channel was
