|
|
The set of events that may be passed to an event callback. erase_event is used during ~ios() and copyfmt(). imbue_event is used during imbue(). copyfmt_event is used during copyfmt(). Definition at line 375 of file ios_base.h. |
|
Invokes each callback with erase_event. Destroys local storage. Note that the ios_base object for the standard streams never gets destroyed. As a result, any callbacks registered with the standard streams will not get invoked with erase_event (unless copyfmt is used). |

Locale access.
imbue(loc) has previously been called, then this function returns loc . Otherwise, it returns a copy of std::locale() , the global C++ locale. Definition at line 647 of file ios_base.h.

Setting a new locale.
Reimplemented in basic_ios.
|
|
Access to integer array.
The implementation reserves several indices. You should use xalloc to obtain an index that is safe to use. Also note that since the array can grow dynamically, it is not safe to hold onto the reference. Definition at line 691 of file ios_base.h. |

Access to unique indices.
The implementation maintains a static variable that is incremented and returned on each invocation. xalloc is guaranteed to return an index that is safe to use in the iword and pword arrays. |
