Exactly what is says.

Do you understand what a switch statement is?

switch(g_messagePrimitives[g_messageCount].msgType)

Look up switch-case expressions. They are quite simple to implement.
Presumably, msgType is an attribute of the elements in the
g_messagePrimitives container (probably a primitive array of messages).
the switch compares the msgType of the specified element with the
available cases available, case-default otherwise.

example:

const int N = 1;
switch( N )
{
case 0:
// do this
break;
case 1:
// do that - this case should be run until break since N == 1
break;
case default:
// do the default action
}

For the record, the switch parameter is a constant and the parameter
should reflect that for readability.

So to answer your question, your switch is running the appropriate case
sequence depending on the message type involved.

By "parameter", are you referring to the part inside the parentheses above?
That's not a constant. The individual case statements within a switch
(assuming there are any) must use constant expressions, but the switch
statement does not. It uses a condition, (which can be either an expression
or the sequence "type-specifier declarator = expression").
