Field Documentation

long _appvar::aes4

bitfield indicating some AES 4 features supported by the OS (see constants AES4_)

short* _appvar::aes_global

The AES global array (use for mt_AES calls).

INT16 _appvar::aeshdl

The screen VDI handle used by AES.

short _appvar::avid

Application AES id of the AV server (or -1).

short _appvar::color

Number of colors of screen display.

int _appvar::error

Last error encountered.

EVNTvar _appvar::evnt

Parameters for evnt_multi() calling.

short _appvar::gdos

Contains the number of fonts loaded (FIXME: should contain the value returns by vq_gdos() ?).

W_GRAFPORT _appvar::graf

Information about the application virtual workstation.

INT16 _appvar::h

Coordinates and size of desktop workarea (not screen size).

OBJECT* _appvar::menu

address of the desktop menu tree

short _appvar::nplanes

Number of planes of screen display (e.g. color = 2^nplanes)

short _appvar::ntree

Number of object trees in the loaded resource.

char* _appvar::pipe

A user buffer used for AES message exchange (more). ApplInit() reserves a 256 byte buffer allocated in global memory mode pointed by this variable. This buffer can be used to send information safely in MU_MESAG event. For example, AV_STARTPROG (AV-protocol) uses app->evnt.buff[3-4] to emit a address pointing to a string character. This address should be app.pipe.

APPRSVD* _appvar::priv

Private variables. Private variables are grouped in a hidden structure in order to prevent their utilisation.

INT16 _appvar::w

WINvar _appvar::wglb

Information about application windows.

INT16 _appvar::work_in[11]

array input of v_opnvwrk() function

INT16 _appvar::work_out[57]

array output of v_opnvwrk() function

INT16 _appvar::x

INT16 _appvar::y
