Summary: Using re2c without a EOF sentinel token
Initial Comment:
Is there a way to use re2c to scan a buffer without the use of a sentinel token
to act as EOF? I want to scan a region between two pointers e.g. I want to run
re2c like:
scan(char *start, char *end) {
/*!re2c
...
*/
}
and only scan data between start and end with no sentinel token like "\0"

Message:
re2c does not have any notion whatsoever of an end token, unless you define
one. Also re2c uses a fill function (or macro) to read the minimum amount
of characters to continue parsing. Obviously if that exaggerates the end
pointer, you have to exit. For that re2c proves enough flexibility.
