# ixp\_pread(3)

## NAME

ixp\_read, ixp\_pread

## SYNOPSIS

```
#include <ixp.h>
long ixp_read(IxpCFid *fid, void *buf, long count);
long ixp_pread(IxpCFid *fid, void *buf, long count, int64_t offset);
```

## PARAMETERS

- buf

  A buffer in which to store the read data.

- count

  The number of bytes to read.

- offset

  The offset at which to begin reading.

## DESCRIPTION

ixp\_read and ixp\_pread each read *count* bytes of data from the file pointed to by *fid*, into *buf*. ixp\_read begins reading at its stored offset, and increments it by the number of bytes read. ixp\_pread reads beginning at *offset* and does not alter *fid*'s stored offset.

## RETURN VALUE

These functions return the number of bytes read on success and -1 on failure.
