int sasl_encode64(const char *in, unsigned inlen, char *out,
unsigned outmax, unsigned *outlen);
Use the sasl_encode64() interface to convert an octet string into a base64 string. This routine is useful for SASL profiles that use base64, such as the IMAP (IMAP4) and POP (POP_AUTH) profiles. The output is null-terminated. If outlen is non-NULL, the length is placed in the outlen.
Input data.
The length of the input data.
The output data. The value of out can be the same as in. However, there must be enough space.
The length of the actual output.
The maximum size of the output buffer.
sasl_encode64() returns an integer that corresponds to a SASL error code.
The call to sasl_encode64() was successful.
