.SH "DESCRIPTION"
.PP
Returns 1 if valid, 0 on error.
If valid, returns pointers to newly allocated GPT header and PTEs.
Validity depends on PMBR being valid (or being overridden by the
'gpt' kernel command line option) and finding either the Primary
GPT header and PTEs valid, or the Alternate GPT header and PTEs
valid.  If the Primary GPT header is not valid, the Alternate GPT header
is not checked unless the 'gpt' kernel command line option is passed.
This protects against devices which misreport their size, and forces
the user to decide to use the Alternate GPT.
