LIBTRACEEVENT(3) libtraceevent Manual LIBTRACEEVENT(3)

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 */
}
