#define INCL_VIO #include <os2.h> PBYTE Cell; /* Attribute to be written. */ ULONG Times; /* Repeat count. */ ULONG Row; /* Starting row position. */ ULONG Column; /* Starting column position. */ HVIO VioHandle; /* VIO presentation-space handle. */ APIRET rc; /* Return code. */ rc = VioWrtNCell(Cell, Times, Row, Column, VioHandle);
Parameters
- Cell (PBYTE) - input
