FSH_REGISTERPERFCTRS

Purpose

This function allows the FSD to register with the PERFVIEW product. The FSD passes pointers to its counter data and text blocks.

Calling Sequence

int far pascal FSH_REGISTERPERFCTRS(pDataBlk, pTextBlk, fsFlags)
 
void far * pDataBlk;
void far * pTextBlk;
unsigned short fsFlags;

Where

pDataBlk is a pointer to the data block where the actual counters reside.

pTextBlk is a pointer to the block that contains instance and name information about counters in the associated DataBlk.

fsFlags indicates what type of addressing is going to be used.

Bit 0 off indicates 16:16 pointers
Bit 0 on indicates 0:32 pointers

All other bits are reserved and must be zero.

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 flag word is invalid.
  • ERROR_PVW_INVALID_COUNTER_BLK – the specified buffer is not in the correct PERFVIEW data block format
  • ERROR_PVW_INVALID_TEXT_BLK – the specified buffer is not in the correct PERFVIEW text block format

Remarks

For a detailed description of the PERFVIEW interface and its associated data structures please see the OS/2 Version 2.0 PERFVIEW OEMI Document.

FSH_REGISTERPERFCTRS may block.

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