.Sh DESCRIPTION
The
.Vt ASN1_STRING
object can represent a variety of ASN.1 built-in types.
It can store a type and a value.
.Pp
All the
.Fn *_new
functions
allocate and initialize an empty
.Vt ASN1_STRING
object.
The following table shows the type assigned to the new object,
and which ASN.1 type it represents.

.El
.Pp
All the
.Fn *_free
functions free
.Fa a
including any data contained in it.
If
.Fa a
is a
.Dv NULL
pointer, no action occurs.
.Sh RETURN VALUES
All the
.Fn *_new
functions return the new
.Vt ASN1_STRING
object if successful; otherwise
.Dv NULL
is returned and an error code can be retrieved with
.Xr ERR_get_error 3 .
