int poptDupArgv	(	int	argc,
		const char **	argv,
		int *	argcPtr,
		const char ***	argvPtr
	)

Duplicate an argument array.

Note:

: The argument array is malloc'd as a single area, so only argv must be free'd.

Parameters:

	argc	no. of arguments
	argv	argument array

Return values:

	argcPtr	address of returned no. of arguments
	argvPtr	address of returned argument array

Returns:

0 on success, POPT_ERROR_NOARG on failure

< missing argument

< missing argument

< memory allocation failed

int poptParseArgvString	(	const char *	s,
		int *	argcPtr,
		const char ***	argvPtr
	)

Parse a string into an argument array.

The parse allows ', ", and \ quoting, but ' is treated the same as " and both may include \ quotes.

Note:

: The argument array is malloc'd as a single area, so only argv must be free'd.

Parameters:

s

string to parse

Return values:

	argcPtr	address of returned no. of arguments
	argvPtr	address of returned argument array

< memory allocation failed

< error in paramter quoting

< error in paramter quoting
