2.1 Function Syntax Conventions

The modular station interface functions use the following syntax:

data_type ms_function(device_handle, parameter1, ... parameterN) 

data type

refers to the data type, such as integer, long or void

ms_function

represents the function name. Typically, modular station interface functions begin with "ms". Extended Attribute functions begin with "ATMS."

device_handle

represents the device handle, which is a numerical reference to a device, obtained when a device is opened. The device handle is used for all operations on that device.

parameter1

represents the first parameter

parameterN

represents the last parameter

Note: Some MSI library functions can operate in either synchronous or asynchronous mode, using a mode parameter. Synchronous functions do not return control to the calling process until the function call is completed. When a function operates in asynchronous mode, the calling process retains control and a completion event is passed to the application to notify that the function is complete.
