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 "OSSL_IETF_ATTR_SYNTAX 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

\fBOSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() and OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority() get and set the policyAuthority field of the structure. Both routines act on internal pointers of the structure and must not be freed by the application.

An OSSL_IETF_ATTR_SYNTAX object also holds a sequence of values. \fBOSSL_IETF_ATTR_SYNTAX_get_value_num() returns the number of values in the sequence. OSSL_IETF_ATTR_SYNTAX_add1_value(), adds a copy of data of a specified \fItype to the sequence. The caller should free the data after use.

\fBOSSL_IETF_ATTR_SYNTAX_get0_value() will return the value and a specific index ind in the sequence or NULL on error. If type is not NULL, the type of the value will be written to this location.

The type of the values stored in the OSSL_IETF_ATTR_SYNTAX value sequence is one of the following:

Item "OSSL_IETFAS_OCTETS" A pointer to an ASN1_OCTET_STRING Item "OSSL_IETFAS_OID" A pointer to an ASN1_OBJECT Item "OSSL_IETFAS_STRING" A pointer to an ASN1_UTF8STRING Header "RETURN VALUES" \fBOSSL_IETF_ATTR_SYNTAX_get0_policyAuthority() returns an pointer to a \fBGENERAL_NAMES structure or NULL if the policy authority has not been set.

\fBOSSL_IETF_ATTR_SYNTAX_get_value_num() returns the number of entries in the value sequence or -1 on error.

\fBOSSL_IETF_ATTR_SYNTAX_get0_value() returns a pointer to the value at the given index or NULL if the index is out of range.

\fBOSSL_IETF_ATTR_SYNTAX_add1_value() returns 1 on success and 0 on failure.

Header "HISTORY" \fBOSSL_IETF_ATTR_SYNTAX_get0_policyAuthority(), OSSL_IETF_ATTR_SYNTAX_set0_policyAuthority(), \fBOSSL_IETF_ATTR_SYNTAX_get_value_num(), OSSL_IETF_ATTR_SYNTAX_get0_value(), and \fBOSSL_IETF_ATTR_SYNTAX_add1_value() were added in OpenSSL 3.4.
