Detailed Description

Table-driven command-line parser.

Defines option metadata, handlers, help rendering, positional-input rules, and the end-of-options marker.

Typedef Documentation

bfc_option_handler_t

typedef bfc_error_t(* bfc_option_handler_t) (bfc_args_t *args, const char *value)

Option callback signature used by the table-driven parser.

Function Documentation

bfc_cmd_help()

void bfc_cmd_help

(

void

)

Renders usage text from the same option table used for parsing.

Prints command-line usage and option descriptions.

bfc_find_option()

const bfc_option_t * bfc_find_option ( const char * argument )

static

Finds option metadata by exact short or long spelling.

bfc_process_args()

bfc_error_t bfc_process_args	(	bfc_args_t *	cmd_args,
		int	argc,
		char *const	argv[] )

Parses options, option values, the end-of-options marker, and one input path.

Parses compiler command-line arguments.

Parses options, option values, the end-of-options marker, and one input path.

Parameters

[out]	cmd_args	Receives zero-initialized parsed arguments.
[in]	argc	Argument count.
