around

you
have

use
a
set
of
API
functions
to
force
a
type
conversion
on
every
argument
that'
s
being
passed
(see
Tabla
32-1
)
.
After retrieving the parameter pointer, the parameter value is
converted to a long (an integer), which also forms the return
value of this function. Understanding access to the contents of
the value requires a short discussion of the
zval
type, whose definition is shown in
Ejemplo
32-2
.
