The ASN1_STRING object can represent a variety of ASN.1 built-in types. It can store a type and a value.

All the () 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.

()
() type argument
() OCTET STRING
() BIT STRING
() INTEGER
() ENUMERATED
() UTF8String
() IA5String
() UniversalString
() BMPString
() GeneralString
() T61String
() VisibleString
() PrintableString
()
()
()
() GeneralizedTime
() UTCTime
() TIME

All the () functions free a including any data contained in it. If a is a NULL pointer, no action occurs.

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).
