Crate MacTypes_sys
source ·Expand description
The MacTypes-sys library provides bindings to the MacTypes.h header on MacOS.
This library defines base types used in both Carbon and legacy Cocoa APIs.

32-bit millisecond timer for drivers.
16-bit signed integer plus 16-bit fraction.
A pointer to a
Fixed.32 bit IEEE float: 1 sign bit, 8 exponent bits, 23 fraction bits.
64 bit IEEE float: 1 sign bit, 11 exponent bits, 52 fraction bits.
A 32-bit value made by packing four 1 byte characters together.
2-bit signed integer plus 30-bit fraction.
A pointer to a
Fract.Pointer to a master pointer to a relocatable block.
32-bit iteration count.
A particular language (e.g. English), as represented using a particular ScriptCode.
Address in the clients virtual address space.
16-bit result error code.
32-bit result error code.
A
FourCharCode used in the OS and file system (e.g. creator).A pointer to an
OSType.Standard 32-bit set of bit flags.
RefCon Types
Real address as used on the hardware bus.
Pointer to a
ProcPtr.Generic pointer to a function.
Pointer to a non-relocatable block.
Designates a language as used in a particular region (e.g. British vs American
English) together with other region-dependent characteristics (e.g. date format).
Pointer to a 68K function that expects parameters in registers.
A
FourCharCode used to tag resources (e.g. DLOG).A pointer to a
ResType.8-bit signed integer.
16-bit signed integer.
32-bit signed integer.
64-bit signed integer.
RefCon Types
A particular set of written characters (e.g. Roman vs Cyrillic) and their encoding.
8-bit signed integer plus 8-bit fraction.
A pointer to a
ShortFixed.Pascal string holding up to 15 bytes
Pascal string holding up to 27 bytes
Pascal string holding up to 31 bytes
The type
Str32 is used in many AppleTalk based data structures.
It holds up to 32 one byte chars. The problem is that with the
length byte it is 33 bytes long. This can cause weird alignment
problems in structures. To fix this the type Str32Field has
been created. It should only be used to hold 32 chars, but
it is 34 bytes long so that there are no alignment problems.Pascal string holding up to 63 bytes
Pascal string holding up to 255 bytes
QuickTime 3.0:
Pointer to a
StringPtr.Pointer to a pascal string.
Quickdraw font rendering styles.
Style when used as a field (historical 68K convention).Style when used as a parameter (historical 68K convention).An opaque reference to a time base.
Units per second.
Count of units.
64-bit count of units (long long or struct).
8-bit unsigned integer.
16-bit unsigned integer.
32-bit unsigned integer.
64-bit unsigned integer.
RefCon Types
An 8-bit code value in UTF-8 format.
UnicodeScalarValues
0-0x7F are expressed in UTF-8 format using one UTF8Char
with the same value. UnicodeScalarValues above 0x7F are
expressed in UTF-8 format using 2-4 UTF8Chars, all with
values in the range 0x80-0xF4 (UnicodeScalarValues
0x100-0xFFFF use two or three UTF8Chars,
UnicodeScalarValues 0x10000-0x10FFFF use four UTF8Chars).A 16-bit Unicode code value in the default UTF-16 format.
UnicodeScalarValues
0-0xFFFF are expressed in UTF-16
format using a single UTF16Char with the same value.
UnicodeScalarValues 0x10000-0x10FFFF are expressed in
UTF-16 format using a pair of UTF16Chars - one in the
high surrogate range (0xD800-0xDBFF) followed by one in
the low surrogate range (0xDC00-0xDFFF). All of the
characters defined in Unicode versions through 3.0 are
in the range 0-0xFFFF and can be expressed using a single
UTF16Char, thus the term “Unicode character” generally
refers to a UniChar = UTF16Char.A complete Unicode character in UTF-32 format, with
values from
0 through 0x10FFFF (excluding the surrogate
range 0xD800-0xDFFF and certain disallowed values).A 16-bit Unicode code value in the default UTF-16 format.
UnicodeScalarValues
0-0xFFFF are expressed in UTF-16
format using a single UTF16Char with the same value.
UnicodeScalarValues 0x10000-0x10FFFF are expressed in
UTF-16 format using a pair of UTF16Chars - one in the
high surrogate range (0xD800-0xDBFF) followed by one in
the low surrogate range (0xDC00-0xDFFF). All of the
characters defined in Unicode versions through 3.0 are
in the range 0-0xFFFF and can be expressed using a single
UTF16Char, thus the term “Unicode character” generally
refers to a UniChar = UTF16Char.A count of UTF-16 code values in an array or buffer.
A pointer to a
UniCharCount.A pointer to an array of
UniChars.A complete Unicode character in UTF-32 format, with
values from
0 through 0x10FFFF (excluding the surrogate
range 0xD800-0xDFFF and certain disallowed values).Pointer to a
UniversalProcPtr.Pointer to classic 68K code or a
RoutineDescriptor.16-bit unsigned integer plus 16-bit fraction.
A pointer to an
UnsignedFixed.Resource Handle containing a
VersRec.Pointer to a
VersRecPtr.The number of bytes in a block (signed for historical reasons).
Unions
NumVersionVariant is a wrapper so NumVersion can be accessed as a 32-bit value.
