NNNNAAAAMMMMEEEE
     SMIME_write_PKCS7 - convert PKCS#7 structure to S/MIME
     format.

SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
      #include 

      int SMIME_write_PKCS7(BIO *out, PKCS7 *p7, BIO *data, int flags);


DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
     SMIME_write_PKCS7() adds the appropriate MIME headers to a
     PKCS#7 structure to produce an S/MIME message.

     oooouuuutttt is the BIO to write the data to. pppp7777 is the appropriate
     PPPPKKKKCCCCSSSS7777 structure. If cleartext signing (mmmmuuuullllttttiiiippppaaaarrrrtttt////ssssiiiiggggnnnneeeedddd) is
     being used then the signed data must be supplied in the ddddaaaattttaaaa
     argument. ffffllllaaaaggggssss is an optional set of flags.

NNNNOOOOTTTTEEEESSSS
     The following flags can be passed in the ffffllllaaaaggggssss parameter.

     If PPPPKKKKCCCCSSSS7777_DDDDEEEETTTTAAAACCCCHHHHEEEEDDDD is set then cleartext signing will be
     used, this option only makes sense for signedData where
     PPPPKKKKCCCCSSSS7777_DDDDEEEETTTTAAAACCCCHHHHEEEEDDDD is also set when PKCS7_sign() is also called.

     If the PPPPKKKKCCCCSSSS7777_TTTTEEEEXXXXTTTT flag is set MIME headers for type
     tttteeeexxxxtttt////ppppllllaaaaiiiinnnn are added to the content, this only makes sense
     if PPPPKKKKCCCCSSSS7777_DDDDEEEETTTTAAAACCCCHHHHEEEEDDDD is also set.

     If the PPPPKKKKCCCCSSSS7777_PPPPAAAARRRRTTTTSSSSIIIIGGGGNNNN flag is set the signed data is
     finalized and output along with the content. This flag
     should only be set if PPPPKKKKCCCCSSSS7777_DDDDEEEETTTTAAAACCCCHHHHEEEEDDDD is also set and the
     previous call to PKCS7_sign() also set these flags.

     If cleartext signing is being used and PPPPKKKKCCCCSSSS7777_PPPPAAAARRRRTTTTSSSSIIIIGGGGNNNN not
     set then the data must be read twice: once to compute the
     signature in PKCS7_sign() and once to output the S/MIME
     message.

BBBBUUUUGGGGSSSS
     SMIME_write_PKCS7() always base64 encodes PKCS#7 structures,
     there should be an option to disable this.

RRRREEEETTTTUUUURRRRNNNN VVVVAAAALLLLUUUUEEEESSSS
     SMIME_write_PKCS7() returns 1 for success or 0 for failure.
