uint8_t* frameBuffer
Examples
SDLvncviewer.c, ppmtest.c, and vnc2mpg.c.

Definition at line 242 of file rfbclient.h.

◆ GetCredential

GetCredentialProc GetCredential

To support security types that requires user input (except VNC password authentication), for example VeNCrypt and MSLogon, this callback function must be set before the authentication.

Otherwise, it implicates that the caller application does not support it and related security types should be bypassed.

Examples
SDLvncviewer.c.

Definition at line 389 of file rfbclient.h.

◆ GetPassword

GetPasswordProc GetPassword

the pointer returned by GetPassword will be freed after use!

Examples
ppmtest.c.

Definition at line 356 of file rfbclient.h.

◆ GotCursorShape

GotCursorShapeProc GotCursorShape

Definition at line 361 of file rfbclient.h.

◆ GotFillRect

GotFillRectProc GotFillRect

Hooks for custom rendering.

VNC rendering boils down to 3 activities:

  • GotCopyRect: copy an area of the framebuffer
  • GotFillRect: fill an area of the framebuffer with a solid color
  • GotBitmap: copy the bitmap in the buffer into the framebuffer The client application should either set all three of these or none!
