Base64Encode Function

Microchip TCP/IP Stack Help

WORD Base64Encode(
    BYTE* cSourceData, 
    WORD wSourceLen, 
    BYTE* cDestData, 
    WORD wDestLen
);

Description

Encodes a binary array to Base-64.

Preconditions

None

Parameters

Parameters	Description
cSourceData	Pointer to a string of binary data
wSourceLen	Length of the binary source data Maximum length that can be written to cDestData
cDestData	Pointer to write the Base-64 encoded data

Returns

Number of encoded bytes written to cDestData. This will always be a multiple of 4.

Remarks

Encoding cannot be performed in-place. If cSourceData overlaps with cDestData, the behavior is undefined.

Encoded data is always at least 1/3 larger than the source data. It may be 1 or 2 bytes larger than that.
