PKCS7_SET_CONTENT(3)       Library Functions Manual       PKCS7_SET_CONTENT(3)

NAME
     PKCS7_set_content, PKCS7_content_new - set the nested contentInfo in a
     PKCS#7 structure

SYNOPSIS
     #include <openssl/pkcs7.h>

     int
     PKCS7_set_content(PKCS7 *outer, PKCS7 *inner);

     int
     PKCS7_content_new(PKCS7 *outer, int inner_type);

DESCRIPTION
     If the contentType of the outer PKCS7 structure is SignedData or
     DigestedData, PKCS7_set_content() sets the contentInfo field of the
     content field of outer to inner, without copying inner.  If there was
     previous contentInfo, it is freed rather than overwritten.  The rest of
     the internal state of outer and of its content remains unchanged.

     PKCS7_content_new() is similar except that it first allocates and
     initializes a new, empty inner object of the given inner_type using
     PKCS7_new(3) and PKCS7_set_type(3).  The inner_type can be any of the
     NIDs listed in the PKCS7_set_type(3) manual.

RETURN VALUES
     These functions return 1 on success or 0 on failure.  They fail if the
     contentType of outer is unsupported.  PKCS7_content_new() can also fail
     when memory is exhausted.  In case of failure, outer remains unchanged.

STANDARDS
     RFC 2315: PKCS #7: Cryptographic Message Syntax Version 1.5

HISTORY
     These functions first appeared in SSLeay 0.8.1 and have been available
     since OpenBSD 2.4.

CAVEATS
     Despite the function names, these functions do not set the content field
     of outer, but only the contentInfo field inside it.  The rest of the
     content remains unchanged.
