How to use the library reference 
The subroutines in the Test subroutine library reference (on page 3-1) are in the C programming 
language. Each subroutine is presented in a standard format that follows the pattern below: 
  Purpose statement: The first line of text under the subroutine heading contains a brief 
explanation of what the subroutine does. 
Figure 1: Example purpose statement 
 
 
  Usage: A line of code representing the prototype of the subroutine, followed by a table listing the 
input and output parameters for the subroutine. Parameters that you specify are shown in 
monospace italic font; parameters preceded by an asterisk (*) are pointers to information 
that is returned. Each parameter is preceded by one of the following declarations that specifies 
the data type for the parameter: int (integer), double (double-precision floating-point), and 
char (a single character value).
