PxIOPositionSeek

Description

Sets a file's index pointer to the specified index position

Format

int PxIOPositionSeek(PxIOFileHandle handle, uint64_t position);

Where:

handle	The handle of an open file
position	The requested index position

Return Value

If the function succeeds, a value of PXIO_SUCCESS_STATUS is returned; otherwise, an error value is returned. More information on the nature of the error can be found by calling PxIOGetError.

Note:
In a keyed file, not all assumed index positions are valid at any given time. For instance, if a keyed file contains a thousand entries, there is no guarantee that index positions 0 to 999 will correspond to legitimate index positions. They are entirely determined by the current state of the file and the sequence in which the records were written.
