#pragma align

#pragma align integer(variable[,variable]...)

Use align to make the listed variables memory-aligned to integer bytes, overriding the default. The following limitations apply:

• integer must be a power of 2 between 1 and 128; valid values are 1, 2, 4, 8, 16, 32, 64, and 128.

• variable is a global or static variable; it cannot be a local variable or a class member variable.

• If the specified alignment is smaller than the default, the default is used.

• The pragma line must appear before the declaration of the variables that it mentions; otherwise, it is ignored.

• Any variable mentioned on the pragma line but not declared in the code following the pragma line is ignored. Variables in the following example are properly declared.
