is_linear_bitmap(3alleg4) Allegro manual is_linear_bitmap(3alleg4)NAME
is_linear_bitmap - Tells if a bitmap is linear. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int is_linear_bitmap(BITMAP *bmp);
DESCRIPTION
Returns TRUE if bmp is a linear bitmap, i.e. a bitmap that can be accessed linearly within each scanline (for example a memory bitmap, the
DOS VGA or SVGA screen, Windows bitmaps, etc). Linear bitmaps can be used with the _putpixel(), _getpixel(), bmp_write_line(), and
bmp_read_line() functions.
Historically there were only linear and planar bitmaps for Allegro, so is_linear_bitmap() is actually an alias for !is_planar_bitmap().

bitmap_mask_color(3alleg4) Allegro manual bitmap_mask_color(3alleg4)NAME
bitmap_mask_color - Returns the mask color of the specified bitmap. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int bitmap_mask_color(BITMAP *bmp);
DESCRIPTION
Returns the mask color for the specified bitmap (the value which is skipped when drawing sprites). For 256-color bitmaps this is zero, and
for truecolor bitmaps it is bright pink (maximum red and blue, zero green). A frequent use of this function is to clear a bitmap with the
mask color so you can later use this bitmap with masked_blit() or draw_sprite() after drawing other stuff on it. Example:
/* Replace mask color with another color. */
for (y = 0; y h; y++)
for (x = 0; x w; x++)
if (getpixel(bmp, x, y) == bitmap_mask_color(bmp))
putpixel(bmp, x, y, another_color);

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
