DESCRIPTION

14       Returns  the  (compiled)  version of the Allegro library, packed into a
15       single   integer   as    groups    of    8    bits    in    the    form
16       (major << 24) | (minor << 16) | (revision << 8) | release.

18       You can use code like this to extract them:
19
20              uint32_t version = al_get_allegro_version();
21              int major = version >> 24;
22              int minor = (version >> 16) & 255;
23              int revision = (version >> 8) & 255;
24              int release = version & 255;
25
26       The  release number is 0 for an unofficial version and 1 or greater for
27       an official release.  For example “5.0.2[1]” would be the (first) offi‐
28       cial  5.0.2  release  while  “5.0.2[0]” would be a compile of a version
29       from the “5.0.2” branch before the official release.
