output PKCS7 structure in PEM
*out, PKCS7 *p7, BIO
*data, int flags);
outputs a PKCS7 structure in PEM format.
It is otherwise identical to the function SMIME_write_PKCS7(3).
This function is effectively a version of PEM_write_bio_PKCS7(3) supporting streaming.
Upon successful completion, 1 is returned; otherwise 0 is returned and an error code can be retrieved with ERR_get_error(3).
