Concepts
CSV Entry Points: Windows
Chapter 130
buffer_length The length (in bytes) of the buffer supplied by the
application to hold the returned data string. The
recommended length is 256 bytes.
buffer_addr The address of the buffer supplied by the application to
hold the returned data string.
Returned Values
The return value from the function is one of the following:
0x00000000 The function completed successfully.
0x20000001 CSV could not read from the supplied VCB, or could not
write to the supplied data buffer.
0x20000002 The supplied data buffer is too small to hold the
returned character string.
0x20000003 The dynamic link library (CSVSTR.DLL for Win16, and
CSVSTR32.DLL for Win32) which generates the
returned character strings for this function, could not
be loaded.
If the return value is 0x00000000, the returned character string is in the
buffer identified by the buffer_addr parameter. This string is
terminated by a null character (binary zero), but does not include a
trailing new-line (\n) character.
