.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIASN1_STRING_new()\fR returns an allocated \fB\s-1ASN1_STRING\s0\fR structure. Its type
is undefined.
.PP
\&\fIASN1_STRING_type_new()\fR returns an allocated \fB\s-1ASN1_STRING\s0\fR structure of
type \fBtype\fR.
.PP
\&\fIASN1_STRING_free()\fR frees up \fBa\fR.
If \fBa\fR is \s-1NULL\s0 nothing is done.
.SH "NOTES"
.IX Header "NOTES"
Other string types call the \fB\s-1ASN1_STRING\s0\fR functions. For example
\&\fIASN1_OCTET_STRING_new()\fR calls ASN1_STRING_type(V_ASN1_OCTET_STRING).
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fIASN1_STRING_new()\fR and \fIASN1_STRING_type_new()\fR return a valid
\&\s-1ASN1_STRING\s0 structure or \fB\s-1NULL\s0\fR if an error occurred.
.PP
\&\fIASN1_STRING_free()\fR does not return a value.
