config_ChainCreate()

char* config_ChainCreate	(	char **	ppsz_name,
		config_chain_t **	pp_cfg,
		const char *	psz_string
	)

This function will parse a configuration string (psz_string) and.

• set the module name (*ppsz_name)
• set all options for this module in a chained list (*pp_cfg)
• returns a pointer on the next module if any.

The string format is module{option=*,option=*}[:modulenext{option=*,...}]

The options values are unescaped using config_StringUnescape.

This function will.

• create all options in the array ppsz_options (var_Create).
• parse the given linked list of config_chain_t and set the value (var_Set).

The option names will be created by adding the psz_prefix prefix.

This function will parse a configuration string (psz_opts) and.

config_StringEscape()

char* config_StringEscape

(

const char *

psz_string

)

This function will escape a string that can be unescaped by config_StringUnescape.

The returned value is allocated by it. You have to free it once you do not need it anymore (unlike config_StringUnescape). If NULL is given as parameter nothing will be done (NULL will be returned).

The escaped characters are ' " and \

config_StringUnescape()

char* config_StringUnescape

(

char *

psz_string

)

This function will unescape a string in place and will return a pointer on the given string.

No memory is allocated by it (unlike config_StringEscape). If NULL is given as parameter nothing will be done (NULL will be returned).

The following sequences will be unescaped (only one time): \ \' and "
