SMIME_TEXT(3) Library Functions Manual SMIME_TEXT(3)

SMIME_textremove text/plain MIME headers

#include <openssl/asn1.h>

SMIME_text(BIO *in_bio, BIO *out_bio);

() 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”.
