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

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