.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "ASN1_STRING_TABLE_add 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
.nh ASN1_STRING_TABLE, ASN1_STRING_TABLE_add, ASN1_STRING_TABLE_get, ASN1_STRING_TABLE_cleanup - ASN1_STRING_TABLE manipulation functions libcrypto, -lcrypto Header "SYNOPSIS" .Vb 1 #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); .Ve Header "DESCRIPTION" Subsection "Types" \fB\s-1ASN1_STRING_TABLE\s0 is a table which holds string information (basically minimum size, maximum size, type and etc) for a \s-1NID\s0 object. Subsection "Functions" \fBASN1_STRING_TABLE_add() adds a new \s-1ASN1_STRING_TABLE\s0 item into the local \s-1ASN1\s0 string table based on the nid along with other parameters.

If the item is already in the table, fields of \s-1ASN1_STRING_TABLE\s0 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 \s-1ASN1_STRING_TABLE\s0 is created and updated with other parameters.

\fBASN1_STRING_TABLE_get() searches for an \s-1ASN1_STRING_TABLE\s0 item based on nid. It will search the local table first, then the standard one.

\fBASN1_STRING_TABLE_cleanup() frees all \s-1ASN1_STRING_TABLE\s0 items added by ASN1_STRING_TABLE_add().

Header "RETURN VALUES" \fBASN1_STRING_TABLE_add() returns 1 on success, 0 if an error occurred.

\fBASN1_STRING_TABLE_get() returns a valid \s-1ASN1_STRING_TABLE\s0 structure or \s-1NULL\s0 if nothing is found.

\fBASN1_STRING_TABLE_cleanup() does not return a value.
