decode()

SINT32 CABase64::decode ( const UINT8 *  in, UINT32  inlen, UINT8 *  out, UINT32 *  outlen  )

static

ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff Makes a Base64-Decoding on the input byte array.

It decodes in to out.

Parameters

in	input byte array
inlen	size of the input byte array
out	output byte array
outlen	on input must contain the size of the byte array for output, on return it contains the size of the decoded output

Return values

E_SUCCESS	if no error occurs
E_UNKNOWN	if an error occurs fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
