NAME¶

tep_is_file_bigendian, tep_set_file_bigendian - Get / set the endianness of the raw data being accessed by the tep handler.

SYNOPSIS¶

#include <event-parse.h>
enum tep_endian {


        TEP_LITTLE_ENDIAN = 0,


        TEP_BIG_ENDIAN
};
bool tep_is_file_bigendian(struct tep_handle *tep);
void tep_set_file_bigendian(struct tep_handle *tep, enum tep_endian endian);

DESCRIPTION¶

The tep_is_file_bigendian() function gets the endianness of the raw data, being accessed by the tep handler. The tep argument is trace event parser context.

The tep_set_file_bigendian() function sets the endianness of raw data being accessed by the tep handler. The tep argument is trace event parser context.

The endian argument is the endianness:


        TEP_LITTLE_ENDIAN - the raw data is in little endian format,


        TEP_BIG_ENDIAN - the raw data is in big endian format.

RETURN VALUE¶

The tep_is_file_bigendian() function returns true if the data is in bigendian format, false otherwise.

EXAMPLE¶

#include <event-parse.h>
...
struct tep_handle *tep = tep_alloc();
...


        tep_set_file_bigendian(tep, TEP_LITTLE_ENDIAN);
...


        if (tep_is_file_bigendian(tep)) {


                /* The raw data is in big endian */


        } else {


                /* The raw data is in little endian */


        }
