.. 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 "S2I_ASN1_IA5STRING 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

This function is used for X509v3 extensions. Header "NOTES" The letters i and s in i2s and s2i stand for \*(L"internal\*(R" (that is, an internal C structure) and string respectively. So i2s_ASN1_IA5STRING() converts from internal to string.

It is the caller's responsibility to free the returned string. In the i2s_ASN1_IA5STRING() function the string is copied and the ownership of the original string remains with the caller.

Header "RETURN VALUES" \fBi2s_ASN1_IA5STRING() returns the pointer to a \s-1IA5\s0 string or \s-1NULL\s0 if an error occurs.

\fBs2i_ASN1_IA5STRING() return a valid \fB\s-1ASN1_IA5STRING\s0 structure or \s-1NULL\s0 if an error occurs.

\fBi2s_ASN1_INTEGER() return a valid string or \s-1NULL\s0 if an error occurs.

\fBs2i_ASN1_INTEGER() returns the pointer to a \s-1ASN1_INTEGER\s0 structure or \s-1NULL\s0 if an error occurs.

\fBi2s_ASN1_OCTET_STRING() returns the pointer to a \s-1OCTET_STRING\s0 string or \s-1NULL\s0 if an error occurs.

\fBs2i_ASN1_OCTET_STRING() return a valid \fB\s-1ASN1_OCTET_STRING\s0 structure or \s-1NULL\s0 if an error occurs.

\fBi2s_ASN1_ENUMERATED() return a valid string or \s-1NULL\s0 if an error occurs.

\fBs2i_ASN1_ENUMERATED() returns the pointer to a \s-1ASN1_ENUMERATED\s0 structure or \s-1NULL\s0 if an error occurs.

\fBs2i_ASN1_UTF8STRING() return a valid \fB\s-1ASN1_UTF8STRING\s0 structure or \s-1NULL\s0 if an error occurs.

\fBi2s_ASN1_UTF8STRING() returns the pointer to a \s-1UTF-8\s0 string or \s-1NULL\s0 if an error occurs.
