int *newBytes)

snap/graphics.h
Parameters
bytesPerLine |
Requested scanline pitch to set |

Description
This function allows the display stride to be changed after the mode has been initialised. Note that this will only work reliabley if the mode was initialised with the gaNoAccel flag, to ensure that the hardware accelerator is not active. This primary use of this function is to allow emulation of VESA VBE/Core functions on top of native SNAP drivers (ie: DOS box support in Windows etc).
