10 | =head1 SYNOPSIS | |
11 | ||
12 | #include <openssl/cmp.h> | |
13 | ||
14 | OSSL_CMP_PKIHEADER *OSSL_CMP_MSG_get0_header(const OSSL_CMP_MSG *msg); | |
62dcd2aa DDO |
15 | OSSL_CMP_MSG *OSSL_d2i_CMP_MSG_bio(BIO *bio, OSSL_CMP_MSG **msg); |
16 | int OSSL_i2d_CMP_MSG_bio(BIO *bio, const OSSL_CMP_MSG *msg); | |

18 | =head1 DESCRIPTION | |
19 | ||
20 | OSSL_CMP_MSG_get0_header returns the header of the given CMP message. | |
21 | ||
62dcd2aa DDO |
22 | OSSL_d2i_CMP_MSG_bio parses an ASN.1-encoded OSSL_CMP_MSG from the BIO I<bio>. |
23 | It assigns a pointer to the new structure to I<*msg> if I<msg> is not NULL. | |
24 | ||
25 | OSSL_i2d_CMP_MSG_bio writes the OSSL_CMP_MSG I<msg> in ASN.1 encoding to BIO I<bio>. | |
26 | ||

29 | CMP is defined in RFC 4210. | |
30 | ||
31 | =head1 RETURN VALUES | |
32 | ||
62dcd2aa | 33 | OSSL_CMP_MSG_get0_header() returns the intended pointer value as described above |
3dbc5156 DDO |
34 | or NULL if the respective entry does not exist and on error. |
35 | ||
62dcd2aa DDO |
36 | OSSL_d2i_CMP_MSG_bio() returns the parsed message or NULL on error. |
