al_itofix - Allegro 5 API
.SH SYNOPSIS
.IP
.nf
\f[C]
#include <allegro5/allegro.h>

al_fixed al_itofix(int x);
\f[R]
.fi
.SH DESCRIPTION
.PP
Converts an integer to fixed point.
This is the same thing as x<<16.
Remember that overflows (trying to convert an integer greater than
32767) and underflows (trying to convert an integer lesser than -32768)
are not detected even in debug builds! The values simply \[lq]wrap
around\[rq].
.PP
Example:
.IP
.nf
\f[C]
al_fixed number;

/* This conversion is OK. */
number = al_itofix(100);
assert(al_fixtoi(number) == 100);

number = al_itofix(64000);

/* This check will fail in debug builds. */
assert(al_fixtoi(number) == 64000);
\f[R]
.fi
.SH RETURN VALUE
.PP
Returns the value of the integer converted to fixed point ignoring
overflows.
