Introduction

The functions reference chapter organizes the list of GXPS driver functions in an alphabetical order. Each function description contains the function name; purpose, syntax, parameters description and type followed by Comments, an Example (written in C), and a See Also sections.

All function and parameter syntax follow the same rules:

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

• The first parameter of most functions is nHandle (16-bit integer). This parameter is required for operating the board and is returned by the GxPsInitialize function. 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 non-zero on error. The description of the error is available using the GxPsGetErrorString function or by using a predefined constant, defined in the driver interface files: GXPS.H, GXPS.BAS, GXPS.VB, GXPS.PAS or GXPS.DRV.
