CMS_UNCOMPRESS(3)		    OpenSSL		     CMS_UNCOMPRESS(3)

NAME
       CMS_uncompress -	uncompress a CMS CompressedData	structure

SYNOPSIS
	#include <openssl/cms.h>

	int CMS_uncompress(CMS_ContentInfo *cms, BIO *dcont, BIO *out, unsigned	int flags);

DESCRIPTION
       CMS_uncompress()	extracts and uncompresses the content from a CMS
       CompressedData structure	cms. data is a BIO to write the	content	to and
       flags is	an optional set	of flags.

       The dcont parameter is used in the rare case where the compressed
       content is detached. It will normally be	set to NULL.

NOTES
       The only	currently supported compression	algorithm is zlib: if the
       structure indicates the use of any other	algorithm an error is
       returned.

       If zlib support is not compiled into OpenSSL then CMS_uncompress() will
       always return an	error.

       The following flags can be passed in the	flags parameter.

       If the CMS_TEXT flag is set MIME	headers	for type text/plain are
       deleted from the	content. If the	content	is not of type text/plain then
       an error	is returned.

RETURN VALUES
       CMS_uncompress()	returns	either 1 for success or	0 for failure. The
       error can be obtained from ERR_get_error(3)

BUGS
       The lack	of single pass processing and the need to hold all data	in
       memory as mentioned in CMS_verify() also	applies	to CMS_decompress().
