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