NAME         top

       tep_is_file_bigendian, tep_set_file_bigendian - Get / set the
       endianness of the raw data being accessed by the tep handler.

SYNOPSIS         top

       #include <event-parse.h>

       enum tep_endian {
               TEP_LITTLE_ENDIAN = 0,
               TEP_BIG_ENDIAN
       };

       bool tep_is_file_bigendian(struct tep_handle *tep);
       void tep_set_file_bigendian(struct tep_handle *tep, enum tep_endian endian);

DESCRIPTION         top

       The tep_is_file_bigendian() function gets the endianness of the
       raw data, being accessed by the tep handler. The tep argument is
       trace event parser context.

       The tep_set_file_bigendian() function sets the endianness of raw
       data being accessed by the tep handler. The tep argument is trace
       event parser context.

           The endian argument is the endianness:
                   TEP_LITTLE_ENDIAN - the raw data is in little endian format,
                   TEP_BIG_ENDIAN - the raw data is in big endian format.

RETURN VALUE         top

       The tep_is_file_bigendian() function returns true if the data is
       in bigendian format, false otherwise.

EXAMPLE         top

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
                   tep_set_file_bigendian(tep, TEP_LITTLE_ENDIAN);
           ...
                   if (tep_is_file_bigendian(tep)) {
                           /* The raw data is in big endian */
                   } else {
                           /* The raw data is in little endian */
                   }
