.SH "DESCRIPTION"
|

.IX Header "DESCRIPTION"
|
|
These functions convert OpenSSL objects to and from their \s-1ASN\s0.1/string
|
|
representation. This function is used for \fBX509v3\fR extentions.
|
|
.SH "NOTES"
|
|
.IX Header "NOTES"
|
|
The letters \fBi\fR and \fBs\fR in \fBi2s_ASN1_IA5STRING\fR() stand for
|
|
\&\*(L"internal\*(R" (that is, an internal C structure) and string respectively.
|
|
So \fBi2s_ASN1_IA5STRING\fR() converts from internal to string.
|
|
.PP
|
|
It is the caller's responsibility to free the returned string.
|
|
In the \fBi2s_ASN1_IA5STRING\fR() function the string is copied and
|
|
the ownership of the original string remains with the caller.
|
|
.SH "RETURN VALUES"
|
|
.IX Header "RETURN VALUES"
