sc_base64_encode 3 opensc sc_base64_encode Encode a stream to base64 #include <opensc.h> int sc_base64_encode(const unsigned char *inbuf, size_t inlen, unsigned char *outbuf, size_t outlen, size_t linelength); This function encodes the buffer pointed to by inbuf of size inlen as base64, and stores the result in outbuf, which is outlen bytes long. A linefeed (\n) will be inserted every linelength bytes in the output buffer. You must ensure outbuf has enough space to store the base64-encoded version of inbuf. Returns 0 if successful, or a negative value in case of error.
