SYNOPSIS

#include <xdfio.h>

struct xdf* xdf_open(const char* filename, int mode,
enum xdffiletype type);

DESCRIPTION

xdf_open() opens a xDF the file refered by the path filename for reading or writing.

If mode is XDF_READ, the file is opened for reading. Thus it must exist and type should be either XDF_ANY or set to the type of the file refered by type. Otherwise, the function will fail.

If mode is XDF_WRITE, the file is opened for writing. Thus the path filename must not refered to an existing file: the function will fail if the file exist. This behavior prevents to overwrite any previous recording. type should be also be set to the desired type of data format (XDF_ANY will result in a error).

The possible file type values are defined in the header file <xdfio.h>

RETURN VALUE

The function returns an handle to xDF file opened in case of success. Otherwise, NULL is returned and errno is set appropriately.
