Detailed Description

A collection of internal implementation functions.

These functions mostly mirror some of those from the public API but are implemented without error checking, or for invocation using already decomposed parameters.

Function Documentation

◆ CheckHandle()

void CheckHandle	(	VPBPortHandle	handle,
		const char *	where
	)

Check for a valid device handle.

The handle is valid if the device has been opened with a prior call to vpb_open().

Exceptions

VpbException will be thrown, stating where, if handle is invalid.

◆ putevt()

int putevt	(	VPB_EVENT *	event,
		unsigned long	mask = `0`
	)

Internal function to place an event on the API event queue.

Parameters

event	The event to place on the API queue.
mask	The mask to use for this event (set to 0 if not required).

References VPB_DEV::APIQ, APIQ, VPB_DEV::callback_mutex, VPB_DEV::context, VPB_DEV::devstate, VPB_DEV::event_callback, VPB_DEV::evtmask, VPB_EVENT::handle, vpb_dev, and VPB_ON.

◆ set_codec_reg()

void set_codec_reg	(	int	handle,
		unsigned short	addr,
		unsigned short	data,
		Comm *	comm
	)

Write directly to a V4PCI codec register.

Parameters

handle	The handle returned by a call to `vpb_open()`.
addr	8-bit address of the codec register.
data	8-bit data to write to the register.
comm	The comm object used to send the message.

Used to set a register of the TS5070 codecs, allows driver-level config of codec, rather than hard-coding in DSP firmware.

References Comm::PutMessageVPB().

◆ validate_digits()

void validate_digits ( const char * digits )

Validate a NULL terminated string of DTMF digits.

Note: this only includes the standard DTMF digits, user defined tone characters will fail if passed here, even if they are valid to be passed to vpb_dial_{a,}sync().

Exceptions

Wobbly will be thrown if any of the digits are not valid.

Referenced by vpb_get_digits_async(), vpb_get_digits_sync(), vpb_play_set(), and vpb_record_set().

◆ vpb_c

extern
