+.IX Item "OSSL_DECODER_from_fp() is only available when OPENSSL_NO_STDIO is undefined."
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBOSSL_DECODER_from_data()\fR runs the decoding process for the context \fIctx\fR,
+with input coming from \fI*pdata\fR, \fI*pdata_len\fR bytes long.  Both \fI*pdata\fR
+and \fI*pdata_len\fR must be non-NULL.  When \fBOSSL_DECODER_from_data()\fR returns,
+\&\fI*pdata\fR is updated to point at the location after what has been decoded,
+and \fI*pdata_len\fR to have the number of remaining bytes.
+.PP
+\&\fBOSSL_DECODER_from_bio()\fR runs the decoding process for the context \fIctx\fR,
+with the input coming from the \fBBIO\fR \fIin\fR.  Should it make a difference,
+it's recommended to have the BIO set in binary mode rather than text mode.
+.PP
+\&\fBOSSL_DECODER_from_fp()\fR does the same thing as \fBOSSL_DECODER_from_bio()\fR,
+except that the input is coming from the \fBFILE\fR \fIfp\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBOSSL_DECODER_from_bio()\fR, \fBOSSL_DECODER_from_data()\fR and \fBOSSL_DECODER_from_fp()\fR
+return 1 on success, or 0 on failure.
