CiRegGetCount()

tCIRC CiRegGetCount	(	tCIp	cip,
		tCIU32 *	nReg
	)

Number of 32b registers.

Parameters

cip	this frame grabber
nReg	returns number of CON registers

CiRegGetFields()

tCIU32 CiRegGetFields	(	tCIp	cip,
		tCIU32	ndx,
		tCIU32 *	ndxAry,
		tCIU32 *	cnt
	)

Return register Field indices.

Query the CON register field indices. These may be used with the CiField* methods to access/modify register sub-fields.

Parameters

cip	this frame grabber
ndx	CON register address in the range 0..nReg-1
ndxAry	32 tCIU32 array of sub-field indices
cnt	the number of sub-field indices

CiRegName()

char* CiRegName	(	tCIp	cip,
		tCIU32	ndx
	)

Return register name.

Query the CON register name. Do not modify the returned string since it is static store.

Parameters

cip	this frame grabber
ndx	CON register address in the range 0..nReg-1

CiRegPeek()

tCIRC CiRegPeek	(	tCIp	cip,
		tCIU32	ndx,
		tCIU32 *	result
	)

< Read a 32b register.

Parameters

cip	this frame grabber
ndx	CON register address in the range 0..nReg-1
result	contents of register

CiRegPoke()

tCIRC CiRegPoke	(	tCIp	cip,
		tCIU32	ndx,
		tCIU32	value,
		tCIU32	mask
	)

Write a 32b register.

Parameters

cip	this frame grabber
ndx	CON register address in the range 0..nReg-1
value	new register value
mask	only modify bits w/'1' in mask
