Detailed Description

hl7 base64 decoder and encoder.

These methods are able to decode hl7 sequence .br\ on a base64 stream

Function Documentation

base64decode()

int base64decode	(	char *	in,
		size_t	inLen,
		unsigned char *	out,
		size_t *	outLen
	)

decode base64 a buffer

Parameters

in	char array to decode
inLen	length of input
out	array holding output
outLen	length of output

Returns

0 on success, 1 invalid input

base64encode()

int base64encode	(	const void *	data_buf,
		size_t	dataLength,
		char *	result,
		size_t	resultSize
	)

encode base64

Parameters

data_buf	char array to encode
dataLength	length of input
result	array holding output
resultSize	length of output

Returns

0 on success, invalid input

hl7_64decode()

int hl7_64decode	(	char *	in,
		size_t	inLen,
		unsigned char *	out,
		size_t *	outLen
	)

decode base64 a buffer

skip \.br\ sequences typically found in hl7 base64 encoded multiline strings.

Parameters

in	char array to decode
inLen	length of input
out	array holding output
outLen	length of output

Returns

0 on success, 1 invalid input, 2 invalid escape sequence

hl7_64decode_fd()

int hl7_64decode_fd	(	char *	in,
		size_t	inLen,
		FILE *	out_fd
	)

decode base64 buffer to a file

skip \.br\ sequences typically found in hl7 base64 encoded multiline strings.

Parameters

in	char array to decode
inLen	length of input
out_fd	file handle to write result to

Returns

0 on success, 1 invalid input, 2 invalid escape sequence
