int dim_data[1][2]={ {250,250} };
char *aperatures[1]= { "1 1 4 a 4 a" };
main()
{
int speed;
char command[64],foo[64];
sprintf(command, "scanregion -da %s %d %d %d /dev/null",aperatures[0],
dim_data[0][0], dim_data[0][1], speed );
sprintf( foo,"echo \"%s \" >>result",command);
printf("%s\n", foo);
sprintf( foo, "time %s >>result 2>&1",command);
printf("%s\n", foo );
}
this Program produces the following output:
echo "scanregion -da 1 1 4 a 4 a 250 250 0 /dev/null " >>result
time >>result 2>&1
I believe it should produce something like:
echo "scanregion -da 1 1 4 a 4 a 250 250 0 /dev/null " >>result
time scanregion -da 1 1 4 a 4 a 250 250 0 /dev/null >>result 2>&1
Any ideas why this might not be so?
These are from a sun-150 with the Sun-2 CPU running Berkley 4.2
In what Sun calls there release 1.1.

Command and foo are too small. Your lines are longer than 64 chars. Program works fine with larger dimensions.

Some of those output lines look longer than 64 characters to me.
A size of only 64 for an array which will be used to build a large
command is most unwise.
