LIBTRACEEVENT(3) libtraceevent ManualLIBTRACEEVENT(3)tep_is_bigendian, tep_is_local_bigendian, tep_set_local_bigendian - Get / set the endianness of the local machine.
#include <event-parse.h> enumtep_endian{ TEP_LITTLE_ENDIAN = 0, TEP_BIG_ENDIAN }; inttep_is_bigendian(void); booltep_is_local_bigendian(struct tep_handle *tep); voidtep_set_local_bigendian(struct tep_handle *tep, enum tep_endianendian);Thetep_is_bigendian()gets the endianness of the machine, executing the function. Thetep_is_local_bigendian()function gets the endianness of the local machine, saved in thetep handler. Thetep argument is the trace event parser context. This API is a bit faster thantep_is_bigendian(), as it returns cached endianness of the local machine instead of checking it each time. Thetep_set_local_bigendian()function sets the endianness of the local machine in thetep handler. Thetep argument is trace event parser context. Theendian argument is the endianness:TEP_LITTLE_ENDIAN - the machine is little endian,TEP_BIG_ENDIAN - the machine is big endian.
Thetep_is_bigendian()function returns non zero if the endianness of the machine, executing the code, is big endian and zero otherwise. Thetep_is_local_bigendian()function returns true, if the endianness of the local machine, saved in thetep handler, is big endian, or false otherwise.
#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");event-parse.h Header file to include in order to have access to the library APIs.-ltraceevent Linker switch to add when building a program that uses the library.
