NT_Entry wpi::nt::GetEntry	(	NT_Inst	inst,
		std::string_view	name )

Get Entry Handle.

Parameters

inst	instance handle
name	entry name (UTF-8 string)

Returns

entry handle

GetEntryFlags()

unsigned int wpi::nt::GetEntryFlags

(

NT_Entry

entry

)

Get Entry Flags.

Parameters

entry

entry handle

Returns

Flags value (bitmask of NT_EntryFlags)

GetEntryLastChange()

int64_t wpi::nt::GetEntryLastChange

(

NT_Handle

subentry

)

Gets the last time the entry was changed.

Returns 0 if the handle is invalid.

Parameters

subentry

subscriber or entry handle

Returns

Entry last change time

GetEntryName()

std::string wpi::nt::GetEntryName

(

NT_Entry

entry

)

Gets the name of the specified entry.

Returns an empty string if the handle is invalid.

Parameters

entry

entry handle

Returns

Entry name

GetEntryType()

NT_Type wpi::nt::GetEntryType

(

NT_Entry

entry

)

Gets the type for the specified entry, or unassigned if non existent.

Parameters

entry

entry handle

Returns

Entry type

GetEntryValue()

(

NT_Handle

subentry

)

Get Entry Value.

Returns copy of current entry value. Note that one of the type options is "unassigned".

Parameters

subentry

subscriber or entry handle

Returns

entry value

ReadQueueValue() [1/2]

std::vector< Value > wpi::nt::ReadQueueValue

(

NT_Handle

subentry

)

Read Entry Queue.

Returns new entry values since last call.

Parameters

subentry

subscriber or entry handle

Returns

entry value array

ReadQueueValue() [2/2]

std::vector< Value > wpi::nt::ReadQueueValue	(	NT_Handle	subentry,
		unsigned int	types )

Read Entry Queue.

Returns new entry values since last call.

Parameters

subentry	subscriber or entry handle
types	bitmask of NT_Type values; 0 is treated specially as a "don't care"

Returns

entry value array

SetDefaultEntryValue()

bool wpi::nt::SetDefaultEntryValue	(	NT_Entry	entry,
		const Value &	value )

Set Default Entry Value.

Returns False if name exists. Otherwise, sets passed in value, and returns True. Note that one of the type options is "unassigned".

Parameters

entry	entry handle
value	value to be set if name does not exist
