Description:

PrtWrite writes data to the device file identified by hDevice.

#include <os2.h>

HFILE     hDevice;    /*  The device handle returned by PrtOpen. */
PVOID     pvoidData;  /*  A pointer to the data buffer. */
ULONG     cData;      /*  The length of the data in bytes. */
PULONG    cWritten;   /*  A pointer to a count of bytes actually written to the device. */
ULONG     rc;         /*  Return codes. */

rc = PrtWrite(hDevice, pvoidData, cData, cWritten);
