NAME

       xdf_open - Open a xDF file for reading or writing

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.

ERRORS

       In addition to the errors related to calls to open(3) or read(3), the following errors can
       occur:

       EILSEQ The file that is being opened does not correspond to a supported file format or  is
              not of the type specified.

       ENOMEM The system is unable to allocate resources.

       EINVAL mode is neither XDF_READ nor XDF_WRITE, or filename is NULL.
