#EMSINIT Built-In Function

Use #EMSINIT to initialize a STRUCT as an event message buffer, preparing it for use

with the other #EMSxxx and #SSxxx built-in functions. This operation gives the buffer

an appropriate header and adds event information to the buffer.

option

is either of these:

SSID ssid

is the subsystem ID of the subsystem to which the subject token belongs. If

omitted or zero (0.0.0), it defaults to the SSID of the subsystem generating the

event.

TIMESTAMP timestamp

is the timestamp, in external representation of four-word Greenwich mean time

format, for the event message. If you omit this parameter, the current time is

used.

buffer-var

is the name of a writable STRUCT to be used as an EMS buffer. #EMSINIT

automatically passes the data length of the STRUCT to the EMSINIT procedure.

Any current contents of the STRUCT are lost.

ssid

is the subsystem ID of the subsystem generating the event.

event-number

is a number, specific to this subsystem, that identifies this event message.

token-id

is the token code of the subject of this event message.

token-value

is the token value in external representation. Its data representation is determined

by the token-type field of token-id.
