You need to pass the address of a variable (ie, &myvar) to i386_get_ioperm(),
which will set your variables to the appropriate values when you call it.
See the manpage:
int
i386_get_ioperm(unsigned int start, unsigned int *length, int *enable);
[ ... ]
DESCRIPTION
i386_get_ioperm() will return the permission for the process' I/O port
space in the *enable argument. The port range starts at start and the
number of contiguous entries will be returned in *length.
