C
WORD Base64Decode( BYTE* cSourceData, WORD wSourceLen, BYTE* cDestData, WORD wDestLen );
Description
Decodes a Base-64 array to its literal representation.
Preconditions
None
Parameters

Parameters |
Description |
|
cSourceData |
Pointer to a string of Base-64 encoded data |
|
wSourceLen |
Length of the Base-64 source data Maximum length that can be written to cDestData |
|
cDestData |
Pointer to write the decoded data |
Returns
Number of decoded bytes written to cDestData.
Remarks
This function is binary safe and will ignore invalid characters (CR, LF, etc). If cSourceData is equal to cDestData, the data will be converted in-place. If cSourceData is not equal to cDestData, but the regions overlap, the behavior is undefined.
Decoded data is always at least 1/4 smaller than the source data.
