DESCRIPTION

17       This function constructs a single entry in an ASN.1 stream, at the
18       buffer pointed to by out (which is outlen bytes long). The tag to be
19       used is in tag, and the entry payload is pointed to by data, which is
20       datalen bytes long.
21
22       If nextbuf is not NULL, it will be filled in with a pointer to the
23       buffer address immediately following the newly copied entry.
