* Transformed std.c.linux.* into wrappers around core.sys.posix modules where appropriate. * Added std.c.osx as the OSX equivalent of std.c.linux. * Added std.c.osx.socket for OSX-specific socket declarations not covered by the Posix spec. * Altered all makefiles to zip, etc, the new std.c.osx package.

D constrains integral types to specific sizes. But efficiency
|
|
of different sizes varies from machine to machine,
|
|
pointer sizes vary, and the maximum integer size varies.
|
|
<b>stdint</b> offers a portable way of trading off size
|
|
vs efficiency, in a manner compatible with the <tt>stdint.h</tt>
|
|
definitions in C.
|
|
|
|
The exact aliases are types of exactly the specified number of bits.
|
|
The at least aliases are at least the specified number of bits
|
|
large, and can be larger.
|
|
The fast aliases are the fastest integral type supported by the
|
|
processor that is at least as wide as the specified number of bits.
|
|
|
|
The aliases are:

The ptr aliases are integral types guaranteed to be large enough
|
|
to hold a pointer without losing bits:

<td>unsigned integral type large enough to hold a pointer
|

|

The max aliases are the largest integral types:
