SMIME_text —
remove text/plain MIME headers
SMIME_text()
reads MIME headers from in_bio, checks that the
content type is “text/plain”, discards the MIME headers, and
copies the text that follows the headers from in_bio
to out_bio.
SMIME_text() returns 1 on success or 0 if
memory allocation, reading the input, or parsing the MIME headers fails, if
there is no “content-type” header, or if the content type is
not “text/plain”.
SMIME_text() first appeared in OpenSSL
1.0.0 and has been available since OpenBSD 4.9.
SMIME_text() does not support non-blocking
BIOs.
