DosQueryDBCSEnv Parameter - pBuf

pBuf (PCHAR) - output

The data area where the country-dependent information for the DBCS environmental vector is returned.

The caller provides this memory area. The size of the area is specified by the input parameter cb.

If this area is too small to hold all of the available information, then as much information as possible is provided in the available space (in the order in which the data would appear). Assuming that the data area is large enough, the valid information is terminated by two bytes of 0. The format of the information returned in this buffer is as follows:

• Bytes
  First range definition for DBCS lead byte values:

  Byte 1

  binary start value (inclusive) for range one
  Byte 2
  binary stop value (inclusive) for range one
  2 Bytes
  Second range definition:

  Byte 1

  binary start value for range two
  Byte 2
  binary stop value for range two
  2 Bytes
  Nth range definition:

  Byte 1

  binary start value for Nth range
  Byte 2
  binary stop value for Nth range
  2 Bytes
  Two bytes of binary 0 end the list.

  For example: DB   81H,9FH
               DB   E0H,FCH
               DB   0,0
