what does unixbf.c do , it is important for the program?

It provides alternative, implementations of C standard library functions
such as fopen(), fread(), etc. That kind of thing is, at best, a
dangerous thing to do. However, it doesn't even compile. It uses FSSpec
as if it were a valid type name, despite the complete absence of any
definition for that identifier anywhere in the code.

Who can help me with creating a makefile for Linux (ubuntu 10.04.3) it

try this one

This is kind of offtopic, but ... it has some features I like
(dependency generation) and some I don't like (a split of header files
and .c files into separate directories; too many variables and
wildcards hiding what's really happening).

And I don't understand what's "visual" or "stupid" about it.

Elsewhere on that site (under ~jhl, obviously):

char *strncpy(char *dst, const char *src, size_t n)
{
char *p = dst;

while (n && (*dst++ = *src++)) n--;
if (!n) *dst = '\0';
return p;
}

Try that with:

char dst[2];
const char src[] = "stupid";
size_t n = sizeof(dst); // n=2
strncpy(dst, src, n); // copies 's', copies 't', breaks loop, writes a \0 - BANG!

Let he who is without stupid cast the first stone.

char *p = dst;



while (n && (*dst++ = *src++)) n--;

if (!n) *dst = '\0';

return p;

}

Are dst and srn non-overlapping in the memeory space? This is a good example in C to teach pointers.

But for a 32-bit cpu a well-tuned memcpy
in assembly is preferred.

Anyway there are 8051, 8052, and 8086 level MCUs on
the markete for applications that focus on cheap parts.

Try that with:



char dst[2];

const char src[] = "stupid";

size_t n = sizeof(dst); // n=2

strncpy(dst, src, n); // copies 's', copies 't', breaks loop, writes a \0- BANG!
