CMS_get0_type(3)						      OpenSSL							  CMS_get0_type(3)

NAME

	CMS_get0_type, CMS_set1_eContentType, CMS_get0_eContentType - get and set CMS content types

SYNOPSIS

	#include <openssl/cms.h>

	const ASN1_OBJECT *CMS_get0_type(CMS_ContentInfo *cms);
	int CMS_set1_eContentType(CMS_ContentInfo *cms, const ASN1_OBJECT *oid);
	const ASN1_OBJECT *CMS_get0_eContentType(CMS_ContentInfo *cms);

DESCRIPTION

       CMS_get0_type() returns the content type of a CMS_ContentInfo structure as and ASN1_OBJECT pointer. An application can then decide how to
       process the CMS_ContentInfo structure based on this value.

       CMS_set1_eContentType() sets the embedded content type of a CMS_ContentInfo structure. It should be called with CMS functions with the
       CMS_PARTIAL flag and before the structure is finalised, otherwise the results are undefined.

       ASN1_OBJECT *CMS_get0_eContentType() returns a pointer to the embedded content type.

NOTES

       As the 0 implies CMS_get0_type() and CMS_get0_eContentType() return internal pointers which should not be freed up. CMS_set1_eContentType()
       copies the supplied OID and it should be freed up after use.

       The ASN1_OBJECT values returned can be converted to an integer NID value using OBJ_obj2nid(). For the currently supported content types the
       following values are returned:

	NID_pkcs7_data
	NID_pkcs7_signed
	NID_pkcs7_digest
	NID_id_smime_ct_compressedData:
	NID_pkcs7_encrypted
	NID_pkcs7_enveloped

RETURN VALUES

       CMS_get0_type() and CMS_get0_eContentType() return and ASN1_OBJECT structure.

       CMS_set1_eContentType() returns 1 for success or 0 if an error occurred.  The error can be obtained from ERR_get_error(3).

       CMS_get0_type(), CMS_set1_eContentType() and CMS_get0_eContentType() were all first added to OpenSSL 0.9.8
