Function Documentation

int __cfg_cfgfile_set_currents	(	const CFG_CONTEXT	con,
		char *	buf
	)

Allocate and initialize variables cur_opt and cur_arg in initialized config file context according to input string (parameter buf).

Parameters

con	initialized command line context
buf	input string

Returns

CFG_OK on success, CFG_ERR_NOMEM on not enough memory error

int __cfg_cmdline_set_currents

(

const CFG_CONTEXT

con

)

Allocate and initialize variables cur_opt and cur_arg in initialized command line context according to con->argv[con->cur_idx].

Parameters

con	initialized command line context

Returns

CFG_OK on success, CFG_ERR_NOMEM on not enough memory error

void __cfg_free_currents

(

const CFG_CONTEXT

con

)

Free current variables (cur_opt, cur_arg) in context and sets cur_opt_type to CFG_NONE_OPTION.

Parameters

con	initialized context with initialized current variables

Returns

void

int __cfg_process_currents	(	const CFG_CONTEXT	con,
		int *	ret_val,
		int *	arg_used
	)

Process current option and argument.

It suppose that in context con are cur_opt, cur_arg and cur_type set.

Parameters

con	initialized context
ret_val	option return value (val)

Parameters

arg_used

if option argument was used

Returns

CFG_OK on success, CFG_ERROR_* on error
