# File Position Functions

PxIOGetNextPosition |

## Description

Retrieves the next record's index position

## Format

int PxIOGetNextPosition(PxIOFileHandle handle , int keyNumber, uint64_t *position) ;

Where:

handle | The handle of an open file
keyNumber | The key number used to specify whether the key is the primary key or one of the alternate keys (if any). If the value passed is -1, then the key sequence will be based on the one previously used with the file handle. The initial key sequence of a file will be the primary one.
position | A pointer to a uint64_t variable used to save the 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:
This function is equivalent to the PxPlus IND( ) function. If the current record is locked, then the retrieved index position will be that of the current record. Otherwise, it will be that of the record following.
