This function queries the system about dynamic system variables and static system variables not returned by DosQSysInfo.

Syntax

FSH_QSYSINFO(index, pData, cbData)

Parameters

index
is the variable to return.
  • index == 1 indicates maximum sector size.
  • index == 2 indicates process identity. The data returned will be as follows:
struct {
   unsigned short PID;
   unsigned short UID;
   unsigned short PDB;
}
  • index == 3 indicates absolute thread number for the current thread. This will be returned in an unsigned short field.
  • index == 4 indicates verify on write flag for the process. This will be returned in an unsigned char (byte) field. Zero means verify is off, non-zero means it is on.
pData
is the long address to the data area.
cbData
is the length of the data area.

Returns

If no error is detected, a zero error code is returned. If an error is detected, one of the following error codes is returned:

  • ERROR_INVALID_PARAMETER the index is invalid.
  • ERROR_BUFFER_OVERFLOW the specified buffer is too short for the returned data.

Calling Sequence

int far pascal FSH_QSYSINFO(index, pData, cbData)

unsigned short index;
char far * pData;
unsigned short cbData;

Remarks

Note
OS/2 does not validate input parameters. An FSD, therefore, should call FSH_PROBEBUF where appropriate.
