NAME

ASN1_STRING_TABLE, ASN1_STRING_TABLE_add, ASN1_STRING_TABLE_get, ASN1_STRING_TABLE_cleanup - ASN1_STRING_TABLE manipulation functions  

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.
