gdb: struct timeval

 
 struct timeval
 ..............
 
 The buffer of type 'struct timeval' used by the File-I/O protocol is
 defined as follows:
 
      struct timeval {
          time_t tv_sec;  /* second */
          long   tv_usec; /* microsecond */
      };
 
    The integral datatypes conform to the definitions given in the
 appropriate section (see SeeIntegral Datatypes, for details) so
 this structure is of size 8 bytes.
