PKCS7_SET_CONTENT(3) FreeBSD 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.

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.
