Description
Decodes an encoded base64 string into the given buffer at the given offset.
This function copies the bytes decoded from a base64 encoded string into a buffer at a given offset. Based on the buffer type, four cases are possible:
buffer_wrap
: If the offset goes beyond the end of the buffer, it is wrapped around to the beginning.buffer_grow
: If there is not enough space in the buffer to store the decoded data, the buffer is resized to be big enoughbuffer_fixed
: If the offset is beyond the end of the buffer, the write is abortedbuffer_fast
: If the offset is beyond the end of the buffer, the write is aborted

Example Call
// demonstrates decoding a base64 encoded registration key from an ini file
