tep_is_bigendian - Man Page

#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​.
