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");
