My friends have some queries which they would like to be helped with :-
Query I - About using fonts in a graphics mode ( currently I am using
800x600x256) under svgalib 1.4.1
vgagl offers a single font of size 8x8, which is very small.
(This font is being used under svgalib using gl_setfont() )
How do I scale this font to a bigger size from within and/or from
outside my program?
Also where do I get different fonts from?
Query II - To get a timing resolution of 10 ms or less under DOS (Turbo
C++ 3.0)
I would like to call a function every 10 ms. (preferably lesser)
WITHOUT making it a TSR or an ISR. The basic requirement is :
void foo()
{
static delayElapsed;
if delayElapsed is > 10 ms return;
.......
.......
}
Currently, I am using the timeb structure which offers a millitm
member but its resolution is 1 CLK_TCK (ie. ~ 54 ms under DOS)
BUT 1 ms under LINUX.
Also, the timeval struct under LINUX offers a microsecond field.
How do I use a common function to measure a time interval as small
as 10 ms or less under both DOS and LINUX ?
