Problem: Displaying MySQL TEXT datatype in C program

Hi,

I'm currently trying to display the contents of a field which datatype
is set to TEXT, I'm trying to output this through a C program.

the line is as follows:

while((row = mysql_fetch_row(result)) != NULL)
{
printf("SID: %d\t\tSensor: %s",(row[1] ? row[1] : "NULL"));
}
I have trued %c and %s in to print the Sensor name, however %s
crashes the program and %c produces a smiley face.

Can anyone pls advise?

Thanks
Thomas
