I'm trying to find the best method of taking input from a TextField and

then using the getCString (or just cString) method to store it to a char

the char * to a Str255 *... I was hoping there was an easier method for
accomplishing this...anyone have any ideas? I come from a Unix /
Windows background, so dealing with Pascal strings is totally foreign to
me...
The CoreFoundation type CFString has functions for obtaining a Pascal
string directly from a CFString. Furthermore CFString and NSString are
bridged, so a non-nil NSString * can be cast to a CFStringRef and used
with the CFString functions. You will need to specify the encoding you
want; this is preferable to using cString and not knowing what encoding
you will get.
