◆ eval_options()

int eval_options	(	int	argc,
		char **	argv,
		struct target_opts *	defaults,
		const char **	exe_opts
	)

Parses command line arguments for switches and options.

Parameters

argc	number of command line arguments.
argv	command line arguments.
defaults	target_status structure containing default values.
exe_opts	handle to default child process arguments string

Returns: number of command line arguments parsed.

Definition at line 435 of file cmdopt.cpp.

◆ split_opt_string()

char ** split_opt_string ( const char * opts )

Translates opts into an array that can be passed to exec().

This method malloc ()s two blocks of memory. The first block is the generated argv index array. This is the return value of this method. The second block is the parsed and split string contents the index referenced.
This block is stored in element 1 of the return array. It is the responsibility of the calling method to free () both blocks.

Warning: this logic is UTF-8 unsafe; I/O redirection command piping isn't supported in the parse logic

Parameters

opts	option string to split

Returns: the parsed argv array
