int apr_base64_decode	(	char *	plain_dst,
		const char *	coded_src
	)

Decode a string to plain text

Parameters

plain_dst	The destination string for the plain text
coded_src	The encoded string

Returns

the length of the plain text string

int apr_base64_decode_binary	(	unsigned char *	plain_dst,
		const char *	coded_src
	)

Decode an EBCDIC string to plain text

Parameters

plain_dst	The destination string for the plain text
coded_src	The encoded string

Returns

the length of the plain text string

int apr_base64_decode_len

(

const char *

coded_src

)

Determine the maximum buffer length required to decode the plain text string given the encoded string.

Parameters

coded_src

The encoded string

Returns

the maximum required buffer length for the plain text string

int apr_base64_encode	(	char *	coded_dst,
		const char *	plain_src,
		int	len_plain_src
	)

Encode a text string using base64encoding.

Parameters

coded_dst	The destination string for the encoded string.
plain_src	The original string in plain text
len_plain_src	The length of the plain text string

Returns

the length of the encoded string

int apr_base64_encode_binary	(	char *	coded_dst,
		const unsigned char *	plain_src,
		int	len_plain_src
	)

Encode an EBCDIC string using base64encoding.

Parameters

coded_dst	The destination string for the encoded string.
plain_src	The original string in plain text
len_plain_src	The length of the plain text string

Returns

the length of the encoded string

int apr_base64_encode_len

(

int

len

)

Given the length of an un-encoded string, get the length of the encoded string.

Parameters

len	the length of an unencoded string.

Returns

the length of the string after it is encoded, including the trailing \0
