# tep\_set\_file\_bigendian(3)

Get / set the endianness of the raw data being accessed by the tep handler.

Part of [tep\_is\_file\_bigendian(3)](/tep_is_file_bigendian/3.md).

## 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 */
        }
```
