Function Documentation

int ix_key_env_get	(	char *	key,
		char *	buffer,
		int	bufferlen
	)

reads key related data from environment to buffer

Parameters:

	key	key of data
	buffer	where data is stored
	bufferlen	length of data storage buffer

Returns:

• length of data
• <0: Error

int ix_key_env_set	(	char *	key,
		char *	buffer
	)

set key related data in environment

Parameters:

	key	key of data
	buffer	zero terminated data buffer

Returns:

• 0: OK
• !0: error

int ix_key_env_unset

(

char *

key

)

unset key related data in environment

Parameters:

key

key of data

Returns:

• 0: OK
• !0: error

int ix_key_file_clear

(

char *

path

)

clear table/file related data

Parameters:

path

absolute path of a file the key data mapping is stored

Returns:

• 0: OK
• !0: error

int ix_key_file_get	(	char *	path,
		char *	key,
		char *	buffer,
		int	bufferlen,
		int *	pflag
	)

reads key and table/file related data and flag from file to buffer

Parameters:

	path	absolute path of a file to store the key data mapping
	key	key of data
	buffer	where data is stored
	bufferlen	length of data storage buffer
	pflag	place to store the flag

Returns:

• length of data
• <0: Error

int ix_key_file_set	(	char *	path,
		char *	key,
		char *	buffer,
		int	flag
	)

stores key and table/file related data and flag in file

Parameters:

	path	absolute path of a file the key data mapping is stored
	key	key of data
	buffer	zero terminated data buffer
	flag	bitfield as integer to store with data

Returns:

• 0: OK
• !0: error

int ix_key_file_unset	(	char *	path,
		char *	key
	)

unset key and table/file related data and flag in file

Parameters:

	path	absolute path of a file the key data mapping is stored
	key	key of data

Returns:

• 0: OK
• !0: error

int ix_key_sizeofdata

(

void

)

returns maximal size of data
