       The tep_read_number() function reads an integer from raw data, taking into account the endianness of the
       raw data and the current host. The tep argument is the trace event parser context. The ptr is a pointer
       to the raw data, where the integer is, and the size is the size of the integer.

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
           void process_record(struct tep_record *record)
           {
                   int offset = 24;
                   int data = tep_read_number(tep, record->data + offset, 4);

                   /* Read the 4 bytes at the offset 24 of data as an integer */
           }
           ...

       The tep_read_number() function returns the integer in the byte order of the current host. In case of an
       error, 0 is returned.
