.Sh NAME
.Nm ASN1_STRING_new ,
.Nm ASN1_STRING_type_new ,

.Nd ASN1_STRING allocation functions
.Sh SYNOPSIS
.In openssl/asn1.h
.Ft ASN1_STRING *
.Fo ASN1_STRING_new
.Fa void
.Fc
.Ft ASN1_STRING *
.Fo ASN1_STRING_type_new
.Fa "int type"

.Fo ASN1_STRING_free
.Fa "ASN1_STRING *a"
.Fc
.Sh DESCRIPTION
.Fn ASN1_STRING_new
returns an allocated
.Vt ASN1_STRING
structure.
Its type is undefined.
.Pp
.Fn ASN1_STRING_type_new
returns an allocated
.Vt ASN1_STRING
structure of type
.Fa type .
.Pp
.Fn ASN1_STRING_free
frees up
.Fa a .
If
.Fa a
is a
.Dv NULL
pointer, no action occurs.
.Pp
Other string types call the ASN1_STRING functions.
For example
.Fn ASN1_OCTET_STRING_new
calls
.Fn ASN1_STRING_type V_ASN1_OCTET_STRING .
.Sh RETURN VALUES
.Fn ASN1_STRING_new
and
.Fn ASN1_STRING_type_new
return a valid
.Vt ASN1_STRING
structure or
.Dv NULL
if an error occurred.
