C-1
C RSC/MP Constants
Table C-1 lists the RSC/MP constants and their values. You can use either the
constant name or the actual value in your code; however, the constant name is more
descriptive to someone not familiar with your code and can be more easily changed.
The constants are listed in the workstation header file (RSC.H). If you are using
constants in your program, include the RSC.H header file at the top of your code.
Users of other languages must convert these constants. The values of the constants
represent a string size for the C language, which includes a NULL terminator and a
filler character. If you are using another language, subtract two from the values listed in
Table C-2 For example, the true value of the RSC_ALIAS_SIZE constant is 30.
Table C-1 and Table C-2 also show the usage of a constant. For example, the
RSC_ALIAS_SIZE constant is used in the UMS header.
