=head1 DESCRIPTION
|
||
|
|
|
||
|
|
=head2 Types
|
||
|
|
|
||
|
|
B<ASN1_STRING_TABLE> is a table which holds string information
|
||
|
|
(basically minimum size, maximum size, type and etc) for a NID object.
|
||
|
|
|
||
|
|
=head2 Functions
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_add() adds a new B<ASN1_STRING_TABLE> item into the
|
||
|
|
local ASN1 string table based on the B<nid> along with other parameters.
|
||
|
|
|
||
|
|
If the item is already in the table, fields of B<ASN1_STRING_TABLE> are
|
||
|
|
updated (depending on the values of those parameters, e.g., B<minsize>
|
||
|
|
and B<maxsize> >= 0, B<mask> and B<flags> != 0). If the B<nid> is standard,
|
||
|
|
a copy of the standard B<ASN1_STRING_TABLE> is created and updated with
|
||
|
|
other parameters.
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_get() searches for an B<ASN1_STRING_TABLE> item based
|
||
|
|
on B<nid>. It will search the local table first, then the standard one.
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_cleanup() frees all B<ASN1_STRING_TABLE> items added
|
||
|
|
by ASN1_STRING_TABLE_add().
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_add() returns 1 on success, 0 if an error occurred.
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_get() returns a valid B<ASN1_STRING_TABLE> structure
|
||
|
|
or B<NULL> if nothing is found.
|
||
|
|
|
||
|
|
ASN1_STRING_TABLE_cleanup() does not return a value.
