• Use the symbolic constant names for parameter values and return codes, not the numeric values shown in the
header file; this ensures that the correct value will be used regardless of the way these values are stored in
memory.
• When accessing SNA sense codes in a data buffer, use the symbolic constants rather than the numeric values;
this ensures that the byte storage order will be correct for your particular system.
• Include a check for return codes other than those applicable to your current operating system (for example using
a “default” case in a switch statement), and provide appropriate diagnostics.
• Ensure that any parameters shown as reserved are set to
0 (zero).
• Set the lua_verb_length parameter as described in Chapter 4, RUI Verbs or Chapter 5, SLI Verbs..
