Implementation Specific Behavior
|
| 1037 |
|
|
|
| 1038 |
|
|
|
| 1039 |
|
|
The ISO standard defines the following phrase:
|
| 1040 |
|
|
|
| 1041 |
|
|
|
| 1042 |
|
|
|
| 1043 |
|
|
|
| 1044 |
|
|
|
| 1045 |
|
|
[1.3.5] implementation-defined behavior
|
| 1046 |
|
|
|
| 1047 |
|
|
|
| 1048 |
|
|
|
| 1049 |
|
|
Behavior, for a well-formed program construct and correct data, that
|
| 1050 |
|
|
depends on the implementation and that each implementation
|
| 1051 |
|
|
shall document.
|
| 1052 |
|
|
|
| 1053 |
|
|
|
| 1054 |
|
|
|
| 1055 |
|
|
|
| 1056 |
|
|
|
| 1057 |
|
|
|
| 1058 |
|
|
We do so here, for the C++ library only. Behavior of the
|
| 1059 |
|
|
compiler, linker, runtime loader, and other elements of "the
|
| 1060 |
|
|
implementation" are documented elsewhere. Everything listed
|
| 1061 |
|
|
in Annex B, Implementation Qualities, are also part of the
|
| 1062 |
|
|
compiler, not the library.
|
| 1063 |
|
|
|
| 1064 |
|
|
|
| 1065 |
|
|
For each entry, we give the section number of the standard, when
|
| 1066 |
|
|
applicable. This list is probably incomplet and inkorrekt.

[1.9]/11 #3 If isatty(3) is true, then

interactive stream support is implied.
|
| 1071 |
|
|
|
| 1072 |
|
|
|
| 1073 |
|
|
[17.4.4.5] Non-reentrant functions are probably best
|
| 1074 |
|
|
discussed in the various sections on multithreading (see above).

|

|
|
[18.3]/8 Even though it's listed in the library
|
| 1084 |
|
|
sections, libstdc++ has zero control over what the cleanup code hands
|
| 1085 |
|
|
back to the runtime loader. Talk to the compiler people. :-)

[18.6.1]/8 (exception),
|
| 1091 |
|
|
[18.6.2.1]/5 (bad_exception): The what()
|
| 1092 |
|
|
member function of class std::exception, and these other
|
| 1093 |
|
|
classes publicly derived from it, simply returns the name of the
|
| 1094 |
|
|
class. But they are the mangled names; you will need to call
|
| 1095 |
|
|
c++filt and pass the names as command-line parameters to
|
| 1096 |
|
|
demangle them, or call a
|
| 1097 |
|
|
runtime demangler function.
|
| 1098 |
|
|
(The classes in <stdexcept> have constructors which
|
| 1099 |
|
|
require an argument to use later for what() calls, so the
|
| 1100 |
|
|
problem of what()'s value does not arise in most
|
| 1101 |
|
|
user-defined exceptions.)
|

|
|
|
| 1103 |
|
|
[18.5.1]/7 The return value of
|
| 1104 |
|
|
std::type_info::name() is the mangled type name (see the
|
| 1105 |
|
|
previous entry for more).

[20.1.5]/5 "Implementors are encouraged to
|
| 1108 |
|
|
supply libraries that can accept allocators that encapsulate more
|
| 1109 |
|
|
general memory models and that support non-equal instances. In such
|
| 1110 |
|
|
implementations, any requirements imposed on allocators by containers
|
| 1111 |
|
|
beyond those requirements that appear in Table 32, and the semantics
|
| 1112 |
|
|
of containers and algorithms when allocator instances compare
|
| 1113 |
|
|
non-equal, are implementation-defined." As yet we don't
|
| 1114 |
|
|
have any allocators which compare non-equal, so we can't describe how
|
| 1115 |
|
|
they behave.

|
| 1122 |
|
|
Nope, these types are called implementation-defined because you
|
| 1123 |
|
|
shouldn't be taking advantage of their underlying types. Listing them
|
| 1124 |
|
|
here would defeat the purpose. :-)

std::ios_base::sync_with_stdio after I/O has already been

|
performed on the standard stream objects will
|
| 1141 |
|
|
flush the buffers, and
|
| 1142 |
|
|
destroy and recreate the underlying buffer instances. Whether or not
|
| 1143 |
|
|
the previously-written I/O is destroyed in this process depends mostly
|
| 1144 |
|
|
on the --enable-libio choice: for stdio, if the written data is
|
| 1145 |
|
|
already in the stdio buffer, the data may be completely safe!

[27.6.1.1.2],

[27.6.2.3] The I/O sentry ctor and dtor can perform

additional work than the minimum required. We are not currently taking

advantage of this yet.
