ИМЯ

       tep_is_bigendian, tep_is_local_bigendian, tep_set_local_bigendian
       - Get / set the endianness of the local machine.

СИНТАКСИС

       #include <event-parse.h>

       enum tep_endian {
               TEP_LITTLE_ENDIAN = 0,
               TEP_BIG_ENDIAN
       };

       int tep_is_bigendian(void);
       bool tep_is_local_bigendian(struct tep_handle *tep);
       void tep_set_local_bigendian(struct tep_handle *tep, enum tep_endian endian);

ОПИСАНИЕ

       The tep_is_bigendian() gets the endianness of the machine,
       executing the function.

       The tep_is_local_bigendian() function gets the endianness of the
       local machine, saved in the tep handler. The tep argument is the
       trace event parser context. This API is a bit faster than
       tep_is_bigendian(), as it returns cached endianness of the local
       machine instead of checking it each time.

       The tep_set_local_bigendian() function sets the endianness of the
       local machine in the tep handler. The tep argument is trace event
       parser context. The endian argument is the endianness:

                   TEP_LITTLE_ENDIAN - the machine is little endian,
                   TEP_BIG_ENDIAN - the machine is big endian.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       The tep_is_bigendian() function returns non zero if the
       endianness of the machine, executing the code, is big endian and
       zero otherwise.

       The tep_is_local_bigendian() function returns true, if the
       endianness of the local machine, saved in the tep handler, is big
       endian, or false otherwise.

ПРИМЕР

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
                   if (tep_is_bigendian())
                           tep_set_local_bigendian(tep, TEP_BIG_ENDIAN);
                   else
                           tep_set_local_bigendian(tep, TEP_LITTLE_ENDIAN);
           ...
                   if (tep_is_local_bigendian(tep))
                           printf("This machine you are running on is bigendian\n");
                   else
                           printf("This machine you are running on is little endian\n");
