SYNOPSIS

11
12        typedef struct asn1_string_table_st ASN1_STRING_TABLE;
13
14        int ASN1_STRING_TABLE_add(int nid, long minsize, long maxsize,
15                                  unsigned long mask, unsigned long flags);
16        ASN1_STRING_TABLE * ASN1_STRING_TABLE_get(int nid);
17        void ASN1_STRING_TABLE_cleanup(void);

DESCRIPTION

20   Types
21       ASN1_STRING_TABLE is a table which holds string information (basically
22       minimum size, maximum size, type and etc) for a NID object.
23
24   Functions
25       ASN1_STRING_TABLE_add() adds a new ASN1_STRING_TABLE item into the
26       local ASN1 string table based on the nid along with other parameters.
27
28       If the item is already in the table, fields of ASN1_STRING_TABLE are
29       updated (depending on the values of those parameters, e.g., minsize and
30       maxsize >= 0, mask and flags != 0). If the nid is standard, a copy of
31       the standard ASN1_STRING_TABLE is created and updated with other
32       parameters.
33
34       ASN1_STRING_TABLE_get() searches for an ASN1_STRING_TABLE item based on
35       nid. It will search the local table first, then the standard one.
36
37       ASN1_STRING_TABLE_cleanup() frees all ASN1_STRING_TABLE items added by
38       ASN1_STRING_TABLE_add().
39

RETURN VALUES

41       ASN1_STRING_TABLE_add() returns 1 on success, 0 if an error occurred.
42
43       ASN1_STRING_TABLE_get() returns a valid ASN1_STRING_TABLE structure or
44       NULL if nothing is found.
45
46       ASN1_STRING_TABLE_cleanup() does not return a value.
