Field Documentation

unsigned int criticalFlag

An unsigned int value that indicates the extension entry's criticality.
.
Extension Criticality Description

NON_CRITICAL Extension is not critical.

CRITICAL Extension is critical.

POINTER reserved

Set this field to NULL_PTR. Reserved for future use.

unsigned int typeLen

An unsigned int value that indicates the length of the extension type. See the tables for the type member.

unsigned int valueCount

An unsigned int value that indicates the number of value entries in the extension entry's value list.

If the extension type can have only one value at a time, the valueCount is 0 (zero) or 1 (one).
If the extension type can have multiple values at the same time, the valueCount is the current number of value entries in the extension's value list.
