Hello Jorge.
To answer the second part of your question:
char buffer[1024];
strcpy(buffer,print_hw_addr (lease -> hardware_addr.htype,
lease -> hardware_addr.hlen,
lease -> hardware_addr.haddr));
char * pos = buffer;
while (*pos != '\0')
{
if (*pos == ':') *pos = '-';
pos++;
}
// and so on....
Using sed in this case is like shooting with cruise missiles on talibans....

Betreff: Re[2]: Sprintf issue
Hello Jorge,
Please, can you check the return value of the system () call ? Also
are you trying to run the compiled program from the cygwin shell or
from the windows command prompt ? Output of cygcheck -r -s -v would
be vuseful too. This is a problem which was brought to the mailing
list some time ago though solution was not found then.
