RegisterConst

Description

int RegisterConst(
   char *Name,
   char *value
);

This function registers a numeric value as a named constant. You can then use the Name as a synonym for the declared value.

Parameters

char *Name

Name.

char *value

String which defines the value of the constant

Return Values

int

Note
