| =head1 NAME |
| |
| ossl_DER_w_begin_sequence, ossl_DER_w_end_sequence |
| - internal DER writers for DER constructed elements |
| |
| =head1 SYNOPSIS |
| |
| #include "internal/der.h" |
| |
| int ossl_DER_w_begin_sequence(WPACKET *pkt, int tag); |
| int ossl_DER_w_end_sequence(WPACKET *pkt, int tag); |
| |
| =head1 DESCRIPTION |
| |
| All functions described here are wrappers for constructed structures, |
| i.e. the ASN.1 SEQUENCE, SET and CHOICE specifications. They all come |
| in pairs, as noted by the function names containing the words C<begin> |
| and B<end>. |
| |
| When using these, special care must be taken to ensure that the ASN.1 tag |
| value I<tag> is the same in the matching C<begin> and C<end> function calls. |
| |
| ossl_DER_w_begin_sequence() and ossl_DER_w_end_sequence() begins and ends a |
| SEQUENCE. |
| |
| =head1 RETURN VALUES |
| |
| All the functions return 1 on success and 0 on failure. Failure may |
| mean that the buffer held by the I<pkt> is too small, but may also |
| mean that the values given to the functions are invalid, such as the provided |
| I<tag> value being too large for the implementation. |
