Description

This function allows you to get information about the event that caused the hook-handler function to be called. MgraGetHookInfo() should only be called within the scope of a 2D graphics list hook-handler function (see MgraHookFunction()).

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 which MIL system’s documentation you should use in its place and any possible differences.

Parameters

This function is not supported on the selected boards.

This function reference has not been updated for the selected MIL system. To show the content of this page, choose a second MIL system; refer to the MIL system's release note to see which MIL system’s documentation to choose and any possible differences.

Parameters

EventId

Specifies the 2D graphics list event identifier received by the hook-handler function (see MgraHookFunction()). The event will be of the type passed to the HookType parameter of the hook-handler function.

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

InfoType

Specifies the type of information to get.

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_DOUBLE
MIL_ID
MIL_INT
