/* Generic File System (GFS)
|
|
GFS allows OS specific access whilst still maintaining 'pure' C-based routines for
|
|
multiplatform compatibility. 'Pure' C-based routines may not allow certain functionality,
|
|
such as partial file locking.
|
|
GFS handles/indexes are independent of QB64 handles/indexes to allow for internal files
|
|
to be open but not intefere with the QB64 file handle numbers.
|
|
|
|
GFS error codes:
|
|
-1 non-specific fail
|
|
-2 invalid handle
|
|
-3 bad/incorrect file mode
|
|
-4 illegal function call (input is out of range)
|
|
-5 file not found (win:2)
|
|
-6 path not found (win:3)
|
|
-7 access/permission denied (win:5,19)
|
|
-8 device unavailable/drive invalid (win:15,21)
|
|
-9 path/file access error
|
|
-10 read past eof
|

-11 bad file name

//MEM_STATIC memory manager
|
|
/*
|
|
mem_static uses a pointer called mem_static_pointer to allocate linear memory.
|
|
It can also change mem_static_pointer back to a previous location, effectively erasing
|
|
any memory after that point.
|
|
Because memory cannot be guaranteed to be allocated in exactly the same location
|
|
after realloc which QB64 requires to keep functionality of previous pointers when
|
|
the current block of memory is full QB64 creates an entirely new block, much larger
|
|
than the previous block (at least 2x), and "writes-off" the previous block as un-
|
|
reclaimable memory. This tradeoff is worth the speed it recovers.
|
|
This allocation strategy can be shown as follows: (X=1MB)
|
|
X
|
|
XX
|
|
XXXX
|
|
XXXXXXXX
|
|
XXXXXXXXXXXXXXXX
|
|
etc.

Aspect ratio determination:

|
32/256 modes always assume 1:1 ratio
|
|
All other modes (1-13) determine their aspect ratio from the destination surface's dimensions (presuming it is stretched onto a 4:3 ratio monitor)
|
|
|
|
Reference:
|
|
Line-drawing and cursor-movement commands:
|
|
D[n%] Moves cursor down n% units.
|
|
E[n%] Moves cursor up and right n% units.
|
|
F[n%] Moves cursor down and right n% units.
|
|
G[n%] Moves cursor down and left n% units.
|
|
H[n%] Moves cursor up and left n% units.
|
|
L[n%] Moves cursor left n% units.
|
|
M[{+|-}]x%,y% Moves cursor to point x%,y%. If x% is preceded
|
|
by + or -, moves relative to the current point.
|
|
-+/- relative ONLY if after the M, after comma doesn't affect method
|
|
-nothing to do with VIEW/WINDOW coordinates (but still clipped)
|
|
R[n%] Moves cursor right n% units.
|
|
U[n%] Moves cursor up n% units.
|
|
[B] Optional prefix that moves cursor without drawing.
|
|
[N] Optional prefix that draws and returns cursor to
|
|
its original position.
|
|
*Prefixes B&N can be used anywhere. They set (not toggle) their respective states. They are only cleared if they are used in a statement. They are forgotten when a new DRAW statement is called.
|
|
Color, rotation, and scale commands:
|
|
An% Rotates an object n% * 90 degrees (n% can be 0, 1,
|
|
2, or 3).
|
|
Cn% Sets the drawing color (n% is a color attribute).
|
|
|
|
Pn1%,n2% Sets the paint fill and border colors of an object
|
|
(n1% is the fill-color attribute, n2% is the
|
|
border-color attribute).
|
|
Sn% Determines the drawing scale by setting the length
|
|
of a unit of cursor movement. The default n% is 4,
|
|
which is equivalent to 1 pixel.
|
|
TAn% Turns an angle n% degrees (-360 through 360).
|
|
|
|
-If you omit n% from line-drawing and cursor-movement commands, the
|
|
cursor moves 1 unit.
|
|
-To execute a DRAW command substring from a DRAW command string, use
|
|
the "X" command:
|
|
DRAW "X"+ VARPTR$(commandstring$)
