ASN1_STRING_TABLE_add(3)            OpenSSL           ASN1_STRING_TABLE_add(3)



NAME
       ASN1_STRING_TABLE, ASN1_STRING_TABLE_add, ASN1_STRING_TABLE_get,
       ASN1_STRING_TABLE_cleanup - ASN1_STRING_TABLE manipulation functions

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/asn1.h>

        typedef struct asn1_string_table_st ASN1_STRING_TABLE;

        int ASN1_STRING_TABLE_add(int nid, long minsize, long maxsize,
                                  unsigned long mask, unsigned long flags);
        ASN1_STRING_TABLE *ASN1_STRING_TABLE_get(int nid);
        void ASN1_STRING_TABLE_cleanup(void);

DESCRIPTION
   Types
       ASN1_STRING_TABLE is a table which holds string information (basically
       minimum size, maximum size, type and etc) for a NID object.

   Functions
       ASN1_STRING_TABLE_add() adds a new ASN1_STRING_TABLE item into the
       local ASN1 string table based on the nid along with other parameters.

       If the item is already in the table, fields of ASN1_STRING_TABLE are
       updated (depending on the values of those parameters, e.g., minsize and
       maxsize >= 0, mask and flags != 0). If the nid is standard, a copy of
       the standard ASN1_STRING_TABLE is created and updated with other
       parameters.

       ASN1_STRING_TABLE_get() searches for an ASN1_STRING_TABLE item based on
       nid. It will search the local table first, then the standard one.

       ASN1_STRING_TABLE_cleanup() frees all ASN1_STRING_TABLE items added by
       ASN1_STRING_TABLE_add().

RETURN VALUES
       ASN1_STRING_TABLE_add() returns 1 on success, 0 if an error occurred.

       ASN1_STRING_TABLE_get() returns a valid ASN1_STRING_TABLE structure or
       NULL if nothing is found.

       ASN1_STRING_TABLE_cleanup() does not return a value.
