Introduction

The GX7016 switching subsystem function reference includes low level GX6192/GX6256/GX6864/RTM/SR functions used to program the digital subsystem components. User should use the SwitchEasy ATEasy command reference to use the digital subsystem. The functions are prefixed with the card type they are addressing (Gx6256, Gx6864, or Gx6192) followed by the main components that they are addressing (SR for switch router, etc.).  The reference chapter is organized in alphabetical order. Each function is presented starting with the syntax of the function, a short description of the function parameters description and type followed by a Comments, an Example (written in C), and a See Also sections.

All function parameters follow the same rules:

• Strings are ASCIIZ (null or zero character terminated).

• Most function’s first parameter is nHandle (16-bit integer). This parameter is required for operating the board and is returned by the GxxxxxInitialize or the GxxxxxInitializeVisa functions. The nHandle is used to identify the board when calling a function for programming and controlling the operation of that board.

• All functions return a status with the last parameter named pnStatus. The pnStatus is zero if the function was successful, or less than a zero on error. The description of the error is available using the GxSWGetErrorString function or by using a predefined constant, defined in the driver interface files: GXSW.H, GXSW.BAS, GXSW.PAS or the ATEasy SwitchEasy driver.

• Parameter name are prefixed as follows:
