The #line directive resets the line numbering, such that
foo = bar * quux; #line 200 bar = pow(baz, 5);
... would cause the second assignment to be treated as being on line 201 for error reporting purposes. The directive can also take a filename as a second argument; thus, if in file craze.c, you had the following code:
foo = bar * quux; #line 1, "sex.c" bar = pow(baz, 5);
... the compiler would report errors following the directive to be treated as if the were numbered starting at line 1 or file sex.c. As with #error, this directive is primarily for used for debugging.
