The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  Keyword:   sizeof
 
  Syntax:    sizeof expression
 
  Summary:   Gives the amount of storage, in bytes, associated with a
             variable or a type (including aggregate types).
 
  See also:  ◄Operators►
 
     The <expression> is either an identifier or a type-cast expression
     (a type specifier enclosed in parentheses).
 
     When applied to a structure type or variable, sizeof returns the
     actual size, which may include padding bytes inserted for
     alignment. When applied to a statically-dimensioned array, sizeof
     returns the size of the entire array. The sizeof operator cannot
     return the size of dynamically-allocated arrays or external arrays.
     For example:
 
          int  i = sizeof( int );
          struct POS                            // sizeof( struct POS )
          {                                     //   may not be two
             char row;                          //   because of alignment
             char col;
          };
          int  array[] = { 1, 2, 3, 4, 5 };     // sizeof( array ) is 10
                                                // sizeof( array[0] ) is 2
          int  sizearr =                        // Count of items in array
            sizeof( array ) / sizeof( array[0] );
