       The tep_strerror() function converts tep error number into a human readable string. The tep argument is
       trace event parser context. The errnum is a regular errno, defined in errno.h, or a tep error number. The
       string, describing this error number is copied in the buf argument. The buflen argument is the size of
       the buf.

       It as a thread safe wrapper around strerror_r(). The library function has two different behaviors - POSIX
       and GNU specific. The tep_strerror() API always behaves as the POSIX version - the error string is copied
       in the user supplied buffer.

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
           char buf[32];
           char *pool = calloc(1, 128);
           if (tep == NULL) {
                   tep_strerror(tep, TEP_ERRNO__MEM_ALLOC_FAILED, buf, 32);
                   printf ("The pool is not initialized, %s", buf);
           }
           ...

       The tep_strerror() function returns 0, if a valid errnum is passed and the string is copied into buf. If
       errnum is not a valid error number, -1 is returned and buf is not modified.
