ulParam1 (ULONG)
This
parameter can contain any of the following flags:
MCI_NOTIFY
A notification message will be posted
to the window specified in the hwndCallback parameter of the data
structure pointed to by the pParam2 parameter. The notification
will be posted when the action indicated by this message is completed or
when an error occurs.
MCI_WAIT
Control
is not to be returned until the action indicated by this message is completed
or an error occurs.
MCI_FROM
Indicates
a starting position is included in the ulFrom field of the data structure
pointed to by pParam2. The units assigned to the position values
are specified with the MCI_SET_TIME_FORMAT flag of the MCI_SET
command. If MCI_FROM is not specified, the starting position defaults
to the current location. The ulFrom field refers to a position in
the destination media.
MCI_TO
Indicates
an ending position is included in the ulTo field of the data structure
pointed to by pParam2. The units assigned to the position values
are specified with the MCI_SET_TIME_FORMAT flag of the MCI_SET
command. If MCI_TO is not specified, the record will continue until
a pause or stop message is received. The ulTo field refers to a
position in the destination media.
MCI_RECORD_INSERT
Indicates that newly recorded information is to
be inserted into existing data at the current location. Some devices, such
as non-file-oriented devices, do not support this.
MCI_RECORD_OVERWRITE
Indicates that recorded data is to overwrite existing
data at the current location. Note that MCI_RECORD_INSERT and MCI_RECORD_OVERWRITE
are mutually exclusive.
