BASE64_SUCCESS

return value for success

(0)

BASE64_ERROR_BUFFER_OUT

error value for invalid output buffer pointer

(-1)

BASE64_ERROR_BUFFER_OUT_SIZE

error value for invalid output buffer size

(-2)

BASE64_ERROR_DATA_IN

error value for invalid input buffer

(-3)

BASE64_ERROR_DATA_IN_SIZE

int base64_encode(const void * data_in, msp430_types.h::size_t data_in_size, unsigned char * base64_out, msp430_types.h::size_t * base64_out_size)

Encodes a given datum to base64 and save the result to the given destination.

Parameters

data_in:pointer to the datum to encode data_in_size:the size of data_in base64_out:pointer to store the encoded base64 string base64_out_size:  pointer to the variable containing the size of base64_out. This value is overwritten with the estimated size used for the encoded base64 string on BASE64_ERROR_BUFFER_OUT_SIZE. This value is overwritten with the actual used size for the encoded base64 string on BASE64_SUCCESS.

Return values

• BASE64_SUCCESS on success, BASE64_ERROR_BUFFER_OUT_SIZE on insufficient size for encoding to base64_out, BASE64_ERROR_BUFFER_OUT if base64_out equals NULL but the base64_out_size is sufficient, BASE64_ERROR_DATA_IN if data_in equals NULL, BASE64_ERROR_DATA_IN_SIZE if data_in_size is less then 1.

int base64_decode(const unsigned char * base64_in, msp430_types.h::size_t base64_in_size, void * data_out, msp430_types.h::size_t * data_out_size)

Decodes a given base64 string and save the result to the given destination.

Parameters

base64_in:pointer to store the encoded base64 string base64_in_size:pointer to the variable containing the size of base64_out. data_out:pointer to the datum to encode data_out_size:the size of data_out. This value is overwritten with the estimated size used for the decoded string on BASE64_ERROR_BUFFER_OUT_SIZE. This value is overwritten with the actual used size for the decoded string on BASE64_SUCCESS.

Return values

• BASE64_SUCCESS on success, BASE64_ERROR_BUFFER_OUT_SIZE on insufficient size for decoding to data_out, BASE64_ERROR_BUFFER_OUT if data_out equals NULL but the size for data_out_size is sufficient, BASE64_ERROR_DATA_IN if base64_in equals NULL, BASE64_ERROR_DATA_IN_SIZE if base64_in_size is less then 4.
