CL_REAL - get a floating point value from a parsed command
line.
Usage:
#include <cl.h>
value = cl_real(cl,index); /* MACRO */
Where:
- CL_PARSED *cl;
- points to a parsed command line structure, as returned by
"cl_cparse" or a related routine.
- int index;
- tells the table entry whose value you want to obtain.
- double value;
- is the floating point value associated with that table
entry. For example, it might be a floating point value
specified with Keyword=number.
Description:
The "cl_real" macro returns a floating point value
associated with an argument or option in a parsed command line.
