   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
   n          I   The number of integer values to compare.
   ...        I   The numbers to be compared, separated by commas.

Detailed_Input

   n           is the number of integer values in the set whose minimum is to
               be determined.

   ...         represents a variable argument list. The number of integer
               values supplied must be that indicated by `n'. The values
               are separated by commas.

               Section 5.2.4.1 of the ANSI C Standard, titled "Translation
               Limits," specifies that argument lists containing at least 31
               items must be supported. In the interest of portability, no
               more than 30 integer values should be supplied.

Detailed_Output

   The function returns the minimum of the set of input integers.

Parameters

   None.

Exceptions

   Error free.

   1)  If `n' is less than 1, the value 0 is returned.

   2)  If the number of integer values supplied does not match
       the argument `n', the action of this routine is not defined.

   3)  If the number of integer values supplied exceeds 30,
       the action of this routine is not defined.

Files

   None.

Particulars

   None.

Examples

   1) Find the minimum of four integer values.

      #include "SpiceUsr.h"
           .
           .
           .

      SpiceInt                min;
      SpiceInt                a;
      SpiceInt                b;
      SpiceInt                c;
      SpiceInt                d;
           .
           .
           .

      min = mini_c ( 4, a, b, c, d );

Restrictions

   1)  The ANSI C Standard specifies that argument lists containing 31
       actual arguments must be supported. Larger sets of values may
       not be handled properly by this routine.
