load_dat_font(3)                Allegro manual                load_dat_font(3)



NAME
       load_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
       simply 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.
