tep_is_file_bigendian - Man Page

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 */
        }
