MseqGetHookInfo

This function allows you to get information about the sequence event that caused the hook-handler function to be called. MseqGetHookInfo() should only be called within the scope of a sequence hook-handler function (see MseqHookFunction()).

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameters

EventId

Specifies the sequence event identifier received by the hook-handler function. See MseqHookFunction() for more information.

InfoType

Specifies a combination of two values: the event type and the type of information about the event to return.

See the Parameter associations section for possible values that can be specified.

UserVarPtr

Accepts the address of one of the following (see the Parameter associations section for specifics on which is expected):

MIL_ID

Specifies the address in which to write the requested information.

See the Parameter associations section for possible values that can be returned.

Parameter associations

The table below lists possible values for the InfoType parameter and possible values returned to the UserVarPtr parameter.

For retrieving the information about a sequence hook event
InfoType		Description
	UserVarPtr - Possible values returned	Description
M_MODIFIED_BUFFER +		Retrieves information about a modified-buffer type of event. This event only occurs if the hook-handler function was hooked using MseqHookFunction(). You must specify a combination value from the following table: To get information about the internal output buffer (summarize) Retrieves information about a modified-buffer type of event. (more details...)
	UserVarPtr data type info	Data type: MIL_ID

Combination constant for M_MODIFIED_BUFFER.

You must add the following value to the above-mentioned value to get information about the internal output buffer.

For retrieving information about the internal output buffer
InfoType		Description
	UserVarPtr - Possible values returned	Description
M_BUFFER_ID		Retrieves the MIL identifier of the internal output buffer modified by MseqProcess(). (summarize) Retrieves the MIL identifier of the internal output buffer modified by MseqProcess(). (more details...)
	UserVarPtr data type info	Data type: MIL_ID

Return value

The returned value is M_NULL if successful. If the operation fails, a non-null (!M_NULL) value is returned.
