=head1 NAME
CMS_uncompress - uncompress a CMS CompressedData structure
=head1 SYNOPSIS
#include <openssl/cms.h>
int CMS_uncompress(CMS_ContentInfo *cms, BIO *dcont, BIO *out, unsigned int flags);
=head1 DESCRIPTION
CMS_uncompress() extracts and uncompresses the content from a CMS
CompressedData structure B<cms>. B<data> is a BIO to write the content to and
B<flags> is an optional set of flags.
The B<dcont> parameter is used in the rare case where the compressed content
is detached. It will normally be set to NULL.
=head1 NOTES
The only currently supported compression algorithm is zlib if the structure
indicates the use of any other algorithm and 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 B<flags> parameter.
If the B<CMS_TEXT> flag is set MIME headers for type B<text/plain> are deleted
from the content. If the content is not of type B<text/plain> then an error is
returned.
=head1 RETURN VALUES
CMS_uncompress() returns either 1 for success or 0 for failure. The error can
be obtained from ERR_get_error(3)
=head1 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().
=head1 SEE ALSO
L<ERR_get_error(3)|ERR_get_error(3)>, L<CMS_compress(3)|CMS_compress(3)>
=head1 HISTORY
CMS_uncompress() was added to OpenSSL 0.9.8
