142 \& #include <openssl/asn1.h>
144 \& typedef struct asn1_string_table_st ASN1_STRING_TABLE;
146 \& int ASN1_STRING_TABLE_add(int nid, long minsize, long maxsize,
147 \& unsigned long mask, unsigned long flags);

149 \& void ASN1_STRING_TABLE_cleanup(void);
152 .IX Header "DESCRIPTION"
154 .IX Subsection "Types"
155 \&\fB\s-1ASN1_STRING_TABLE\s0\fR is a table which holds string information
156 (basically minimum size, maximum size, type and etc) for a \s-1NID\s0 object.
158 .IX Subsection "Functions"
159 \&\fIASN1_STRING_TABLE_add()\fR adds a new \fB\s-1ASN1_STRING_TABLE\s0\fR item into the
160 local \s-1ASN1\s0 string table based on the \fBnid\fR along with other parameters.
162 If the item is already in the table, fields of \fB\s-1ASN1_STRING_TABLE\s0\fR are
163 updated (depending on the values of those parameters, e.g., \fBminsize\fR
164 and \fBmaxsize\fR >= 0, \fBmask\fR and \fBflags\fR != 0). If the \fBnid\fR is standard,
165 a copy of the standard \fB\s-1ASN1_STRING_TABLE\s0\fR is created and updated with
168 \&\fIASN1_STRING_TABLE_get()\fR searches for an \fB\s-1ASN1_STRING_TABLE\s0\fR item based
169 on \fBnid\fR. It will search the local table first, then the standard one.
171 \&\fIASN1_STRING_TABLE_cleanup()\fR frees all \fB\s-1ASN1_STRING_TABLE\s0\fR items added
172 by \fIASN1_STRING_TABLE_add()\fR.
174 .IX Header "RETURN VALUES"
175 \&\fIASN1_STRING_TABLE_add()\fR returns 1 on success, 0 if an error occurred.
177 \&\fIASN1_STRING_TABLE_get()\fR returns a valid \fB\s-1ASN1_STRING_TABLE\s0\fR structure
178 or \fB\s-1NULL\s0\fR if nothing is found.
180 \&\fIASN1_STRING_TABLE_cleanup()\fR does not return a value.
