+.SH NAME
+ftell, ftello \- return a file offset in a stream
+.SH SYNOPSIS
+.LP
+.nf
+#include <stdio.h>
+
+\fBlong\fR \fBftell\fR(\fBFILE *\fR\fIstream\fR);
+.fi
+
+.LP
+.nf
+\fBoff_t\fR \fBftello\fR(\fBFILE *\fR\fIstream\fR);
+.fi
+
+.SH DESCRIPTION
+.sp
+.LP
+The \fBftell()\fR function obtains the current value of the file-position
+indicator for the stream pointed to by \fIstream\fR. The \fBftello()\fR
+function is identical to \fBftell()\fR except for the return type.
+.SH RETURN VALUES
+.sp
+.LP
+Upon successful completion, the \fBftell()\fR and \fBftello()\fR functions
+return the current value of the file-position indicator for the stream measured
+in bytes from the beginning of the file. Otherwise, they return \fB\(mi1\fR and
+sets \fBerrno\fR to indicate the error.
+.SH ERRORS
+.sp
+.LP
+The \fBftell()\fR and \fBftello()\fR functions will fail if:
+.sp
+.ne 2
+.mk
+.na
+\fB\fBEBADF\fR\fR
+.ad
+.RS 10n
+.rt
+The file descriptor underlying \fIstream\fR is not an open file descriptor.
+.RE
+
+.sp
+.ne 2
+.mk
+.na
+\fB\fBESPIPE\fR\fR
+.ad
+.RS 10n
+.rt
+The file descriptor underlying \fIstream\fR is associated with a pipe, a FIFO,
+or a socket.
+.RE

+.sp
+.LP
+The \fBftell()\fR function will fail if:
+.sp
+.ne 2
+.mk
+.na
+\fB\fBEOVERFLOW\fR\fR
+.ad
+.RS 13n
+.rt
+The current file offset cannot be represented correctly in an object of type
+\fBlong\fR.

+The current file offset cannot be represented correctly in an object of type

+.RE
+
+.SH USAGE
+.sp
+.LP
+The \fBftello()\fR function has a transitional interface for 64-bit file
+offsets. See \fBlf64\fR(5).
