NAME

xdf_seek - move the sample pointer of a xDF file

SYNOPSIS

#include <xdfio.h>

off_t xdf_seek(struct xdf* xdf , off_t offset , int whence );

DESCRIPTION

xdf_seek () repositions the current sample pointer according to the couple ( offset , whence ) where whence can be:
SEEK_SET

The offset is set to offset bytes.

SEEK_CUR

The offset is set to its current location plus offset bytes.

SEEK_END

The offset is set to the size of the file plus offset bytes.

The file referenced by xdf should have been opened with mode XDF_READ and xdf_prepare_arrays (3) should have been successfully called on it.

RETURN VALUE

Upon successful completion, xdf_seek () returns the resulting offset location as measured in number of samples from the beginning of the recording. Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

	EINVAL		xdf is NULL or whence is none of the allowed values.
	EPERM		No successfull call to xdf_prepare_transfer (3) have been done on xdf or it has been opened using the mode XDF_WRITE .
	ERANGE		The requested offset is out of the range of the recording.
	EINTR		The call was interrupted by a signal before any data was read; see signal (7).
	EIO		A low-level I/O error occurred while reading from the inode.
	ESTALE		Stale file handle. This error can occur for NFS and for other file systems
