To name a section, the first * non-whitespace character on the line will be '[', and the last will be ']'. * * Parameters are simple key=value pairs. Whitespace around the '=', and at the * beginning or end of the line is ignored. Key names may not contain '=' nor * begin with '[', however values can. If the last character of the value is * '\', the next line (sans leading/trailing whitespace) is considered part of * the value as well. Programmatically, the key "K" in section "S" is referred * to as "S::K", much like C++ namespaces. For example: * [Section1] * # this is a comment * foo = bar \ * baz\ * quux \ * # this is not a comment! * means the value of "Section1::foo" is "bar bazquux # this is not a comment!" * * Parameters may be of several types: * String - Bare characters. If the first and last characters are both '"', * they are removed (so just double them if you really want quotes * there) * Int - A decimal number from -2147483648 to 2147483647 * UInt - A number in decimal, hex, or octal from 0 to 4294967295 (or * 0xffffffff, or 037777777777) * Bool - true/false, 0/1, on/off, yes/no * * Of course, the actual accepted values for a parameter may be further * restricted ;) */ /* You must write this for your port */ void S9xParsePortConfig(ConfigFile &, int pass); /* This may or may not be useful to you */ char *S9xParseDisplayConfig(ConfigFile &, int pass); #endif
