Functions
option_t *	option_lookup (gchar letter, option_t *ovec, gint osize)
	Locate the option letter in the vector array, returning the pointer to the entry if found, or NULL if it wasn't.
const gchar *	options_parse_last_error (void)
	Returns error string resulting from the last call to options_parse().
gint	options_parse (const gchar *argv[], option_t *ovec, gint osize)

Function Documentation

option_t* option_lookup (  gchar  letter, option_t *  ovec, gint  osize )  [static]

Locate the option letter in the vector array, returning the pointer to the entry if found, or NULL if it wasn't.

gint options_parse (  const gchar *  argv[], option_t *  ovec, gint  osize )

Parse the arguments, looking for specific single-letter options. Whenever an option is found, the value in the option_t vector is set. Options start with a "-" and option parsing stops when "--" is encountered. Several argumentless options can be concatenated together after the initial "-". The value of the option can immediately follow the option letter, or be given by the next argument. Unrecognized options or missing arguments stop processing. Parameters: argv  the initial argument vector ovec  the single-letter option description vector osize  the amount of entries in ovec Returns: The number of options processed and validated, -1 on error.

const gchar* options_parse_last_error (  void   )

Returns error string resulting from the last call to options_parse().
