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.
