Detailed Description

Parse command-line arguments, set up the global program arguments data structure.

Function Documentation

static void print_args ( void  )

static

Log the global program arguments data structure.

char* args_canonpath	(	const char *	path,
		uint8_t	create
	)

Validate and canonicalize a path.

Parameters

path	Path to validate
create	Flag: Test creating nonexistent path, mode 0644?

Returns

A newly allocated C string containing the canonicalized path if successful, or NULL if unsuccessful

Note

If successful, caller is responsible for free(3)ing the result
