60 argument specifies the system variable to be queried.
61 Symbolic constants for each name value are found in the include file
65 argument specifies the size of the buffer referenced by the
72 is a non-null pointer, and
76 \- 1 bytes of the value are copied into the buffer
78 The copied value is always null terminated.
80 The available values are as follows:
85 Return a value for the

92 is not successful, \-1 is returned and
