Sets the current position of the specified open fork.

void PBSetForkPositionAsync (
    FSForkIOParam *paramBlock
);

paramBlock

A pointer to a parameter block

DISCUSSION

The relevant fields of the parameter block are:

• ioCompletion

  On input, a pointer to a completion routine.

• ioResult

  On output, the result code of the function.

• forkRefNum

  On input, the reference number of the fork.

• positionMode

  On input, the base location for the new position. If positionMode is equal to fsAtMark, then the positionOffset parameter is ignored. See “Position Mode Constants” for a description of the constants you can use here.

• positionOffset

  On input, the offset of the new position from the base.

AVAILABILITY
