Can someone explain to me what is wrong with using '\0' or even 0 when a
zero byte is required. Is there ever a possibility that NULLchar or
whatever will evaluate to anything but a zero byte. Perhaps this is for
people who get paid by the line of code.
Let's see. If I was paid by the line of code ...
#define IF if
#define ELSE else
#define LOOP_WHILE_STATEMENT_TRUE(x) while(x)
#define DO_IF_STATEMENT_TRUE(x) IF(x)
etc
I bet I could turn "Hello, world" into a major GNU project. :-)
