const char* spot::option_map::parse_options ( const char *  options)

Add the parsed options to the map.

options are separated by a space, comma, semicolon or tabulation and can be optionnaly followed by an integer value (preceded by an equal sign). If not specified, the default value is 1.

The following three lines are equivalent.

optA=1, optB=0, optC=4096K
optC = 4M; optA !optB
Returns
A non-null pointer to the option for which an expected integer value cannot be parsed.
int spot::option_map::set ( const char *  option,
int  val,
int  def = 0
