load_dat_font(3) Allegro manual load_dat_font(3)NAMEload_dat_font - Loads a FONT from an Allegro datafile.
SYNOPSIS
#include <allegro.h>
FONT *load_dat_font(const char *filename, RGB *pal, void *param)
DESCRIPTION
Loads a FONT from an Allegro datafile. You can set param parameter to
point to an array that holds two strings that identify the font and the
palette in the datafile by name. The first string in this list is the
name of the font. You can pass NULL here to just load the first font
found in the datafile. The second string can be used to specify the
name of the palette associated with the font. This is only returned if
the pal parameter is not NULL. If you pass NULL for the name of the
palette, the last palette found before the font was found is returned.
You can also pass NULL for param, which is treated as if you had passed
NULL for both strings separately. In this case, the function will sim‐
ply load the first font it finds from the datafile and the palette that
precedes it.
For example, suppose you have a datafile named `fonts.dat' with the
following contents:
FONT FONT_1_DATA
FONT FONT_2_DATA
FONT FONT_3_DATA
PAL FONT_1_PALETTE
PAL FONT_2_PALETTE
Then the following code will load FONT_1_DATA as a FONT and return
FONT_1_PALETTE as the palette:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_1_DATA", "FONT_1_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If instead you want to load the second font, FONT_2, from the datafile,
you would use:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_2_DATA", "FONT_2_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If you want to load the third font, but not bother with a palette, use:
FONT *f;
char *names[] = { "FONT_3_DATA", NULL }
f = load_dat_font("fonts.dat", NULL, names);
RETURN VALUE
Returns a pointer to the font or NULL on error. Remember that you are
responsible for destroying the font when you are finished with it to
avoid memory leaks.
