| 13 | .SH DESCRIPTION |
|---|
| 14 | This function is similar to the |
|---|
| 15 | .IR "aio_read" |
|---|
| 16 | function. The only |
|---|
| 17 | difference is that on |
|---|
| 18 | .IR "32 bit" |
|---|
| 19 | machines, the file descriptor should |
|---|
| 20 | be opened in the large file mode. Internally, |
|---|
| 21 | .IR "aio_read64" |
|---|
| 22 | uses |
|---|
| 23 | functionality equivalent to |
|---|
| 24 | .IR "lseek64" |
|---|
| 25 | to position the file descriptor correctly for the reading, |
|---|
| 26 | as opposed to |
|---|
| 27 | .IR "lseek" |
|---|
| 28 | functionality used in |
|---|
| 29 | .IR "aio_read". |
|---|
| 30 | |
|---|
| 31 | When the sources are compiled with |
|---|
| 32 | .IR "_FILE_OFFSET_BITS == 64" |
|---|
| 33 | , this |
|---|
| 34 | function is available under the name |
|---|
| 35 | .IR "aio_read" |
|---|
| 36 | and so transparently |
|---|
| 37 | replaces the interface for small files on 32 bit machines. |
