Command Line Format
PAck = { 1 | 2}
Description
Specifies the boundary alignment of structure, union, and class members.
Boundary alignment of structure members can also be specified by the #pragma pack
extension. If both this option and #pragma are specified, only #pragma is valid.
The boundary alignment of structures, unions, and classes equals to the maximum boundary
alignment of members.
For details, refer to section 10.1.2 (2), Compound Type (C), Class Type (C++).
When this option is not specified, the compiler assumes that pack=2 is specified.
Remarks
Table 2.11 shows the boundary alignment of structure, union, and class members when pack is
specified.
A member of a struct, union or class to which the pack=1 option or #pragma pack 1 is
specified must not be accessed via a pointer (including an access via a pointer in a member
function).
