MMPACTION

The MMPACTION structure contains information about a movie file script-channel command.

typedef struct tagMMPACTION {
    BYTE  bMenuItem;
    BYTE  bActionCode;
    WORD  wTextOffset;
} MMPACTION;

Fields

The MMPACTION structure has the following fields:

bMenuItem

Specifies the menu item number from the script-channel window.

bActionCode

Not used by Movie Player.

wTextOffset

Specifies the offset of the script-channel text from the start of the action text block.

Comments

The action text is stored in packed format, without terminating NULL characters. To determine the length of an action-text entry, subtract the wTextOffset value of the action entry from the wTextOffset value of the next action entry in the list. The action-entry list contains one action entry beyond the count of action-code entries returned by the mmpGetInfo function. The wTextOffset value of the last MMPACTION structure indexes one byte beyond the end of the action-code text.
