| +=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 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 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().
