# File Position Functions

PxIOGetKeyPosition |

## Description

Retrieves the index position of the record corresponding to a specified key and key number

## Format

int PxIOGetKeyPosition(PxIOFileHandle handle, KeyInfo *key, int keyNumber, uint64_t *position);

Where:

handle | The handle of an open keyed file
key | Pointer to a KeyInfo structure containing key information used as the basis to determine the index position.
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.
