VioReadCellStr
Bindings: C, MASM
This call reads a string of character-attribute pairs (cells) from the
screen, starting at the specified location.
VioReadCellStr (CellStr, Length, Row, Column, VioHandle)
CellStr (PCH) - output
Address of the buffer where the cell string is returned.
Length (PUSHORT) - input/output
Address of the buffer length in bytes. Length must take into account
that each character-attribute(s) entry in the buffer is 2 or 4 bytes.
If the length of the buffer is not sufficient, the last entry is not
complete.
Row (USHORT) - input
Starting row of the field to read, 0 is the top row.
Column (USHORT) - input
Starting column of the field to read, 0 is the leftmost column.
VioHandle (HVIO) - input
This must be zero unless the caller is a Presentation Manager
application, in which case it must be the value returned by VioGetPs.
rc (USHORT) - return
Return code descriptions are:
0 NO_ERROR
355 ERROR_VIO_MODE
358 ERROR_VIO_ROW
359 ERROR_VIO_COL
436 ERROR_VIO_INVALID_HANDLE
465 ERROR_VIO_DETACHED
Remarks
If a string read comes to the end of the line and is not complete, the
string read continues at the beginning of the next line. If the read
comes to the end of the screen and is not complete, the read terminates
and the length is set to the length of the buffer that was filled.
PM Considerations
VioReadCellStr reads a string of character/attributes (or cells) from the
Advanced VIO presentation space starting at the specified location.
