Function Documentation

pj_status_t pj_base64_decode	(	const pj_str_t *	input,
		pj_uint8_t *	out,
		int *	out_len
	)

Decode base64 string.

Parameters:

input	Input string.
out	Buffer to store the output. Caller must allocate this buffer with the appropriate size.
out_len	On entry, it specifies the length of the output buffer. Upon return, this will be filled with the actual length of the output.

pj_status_t pj_base64_encode	(	const pj_uint8_t *	input,
		int	in_len,
		char *	output,
		int *	out_len
	)

Encode a buffer into base64 encoding.

Parameters:

input	The input buffer.
in_len	Size of the input buffer.
output	Output buffer. Caller must allocate this buffer with the appropriate size.
out_len	On entry, it specifies the length of the output buffer. Upon return, this will be filled with the actual length of the output buffer.

Returns:

PJ_SUCCESS on success.
