Here is the caller graph for this function:

int cfg_parse_section	(	void *	param,
		struct cfg_parser *	st,
		unsigned int	flags
	)

The function expects parameter param to be of type (str*). The result string is allocated using pkg_malloc and is zero terminated. To free the memory use pkg_free(((str*)param)->s)

Here is the call graph for this function:

cfg_parser_t* cfg_parser_init	(	str *	basedir,
		str *	filename
	)			`[read]`

Parameters:

	basedir	- path to the config file name. If 0 the path (base directory) of the main ser.cfg file will be used, else basedir will be concatenated to the filename. It will be used only if filename is not an absolute path.
	filename	- config filename (can include path elements).

Returns:: 0 on error, !=0 on success.
