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 */
            }
