| 24 | .SH NAME | |
| 25 | fseeko, ftello \- seek to or report file position | |
| 26 | .SH SYNOPSIS | |
| 27 | .nf | |
| 28 | .B #include <stdio.h> | |
| 29 | .sp | |
| 30 | .BI "int fseeko(FILE *" stream ", off_t " offset ", int " whence ); | |

| 35 | .SH DESCRIPTION | |
| 63aa9df0 MK |
36 | The \fBfseeko\fP() and \fBftello\fP() functions are identical to |
| 37 | \fBfseek\fP() and \fBftell\fP() (see | |
| fea681da | 38 | .BR fseek (3)), |
| 63aa9df0 MK |
39 | respectively, except that the \fIoffset\fP argument of \fBfseeko\fP() |
| 40 | and the return value of \fBftello\fP() is of type \fBoff_t\fP | |
| fea681da MK |
41 | instead of \fBlong\fP. |
| 42 | .LP | |
| 43 | On many architectures both \fBoff_t\fP and \fBlong\fP are 32-bit types, | |
| 44 | but compilation with | |
| 45 | .RS | |
| 46 | .nf | |
| 47 | #define _FILE_OFFSET_BITS 64 | |
| 48 | .fi | |
| 49 | .RE | |
| 50 | will turn \fBoff_t\fP into a 64-bit type. | |
| 51 | .SH NOTES | |
| 52 | These functions are found on SysV-like systems. | |
| 53 | They are not present in libc4, libc5, glibc 2.0 but available since glibc 2.1. | |
| 54 | .SH "CONFORMING TO" | |
| 55 | The | |

| fea681da | 57 | and |
| e511ffb6 | 58 | .BR ftello () |
| fea681da MK |
59 | functions conform to SUSv2. |
