Hello Monks,
I have this script here that is designed to read through a bin file 32 bits at a time and add each 32 bits to the checksum. however, whenever i run this script, the print is never returned. Am i doing something wrong? Also, is the & symbol used to restrain the read to 32 bits?
sub cksum{
my $word_count;
my $bias=0;
my $checksum=0;
my $srcfile="../vxWorks.dsu_flt-rom.bin";
my $buffer;
open INF, $srcfile
or die "\nCan't open $srcfile for reading: $!\n";
print "Cannot open file.\n";
binmode INF;
$checksum = $bias;
#while ($word_count>=0)
while (
read (INF, $buffer, 32) #and print OUTF $buffer
+# exit if read or write fails
)
{$checksum = $checksum + $buffer}; #adding goes here
$checksum = $checksum & 0xFFFFFFFF;
print "This is the checksum: $checksum";
}
Thanks in advanced for your help.
