Libc, lib(std)c and libfmt are all linked as shared libraries to compare formatting function overhead only. Boost Format is a header-only library so it doesn't provide any linkage options. Boost Format is a header-only library so it doesn't provide any linkage options. C (Cpp) PaCloseStream - 30 examples found. These are the top rated real world C (Cpp) examples of PaCloseStream extracted from open source projects. You can rate examples to help us improve the quality of examples.
std::basic_ostream- They are two different code std::ostream/code objects that map to two different file descriptors of the OS (namely: 1 and 2). By default they both map to the console output, but they can be redirected in different devices or files.
- I'm doing something trying to involve a null output stream, i.e. A stream that just discards what goes into it. Try searching comp.lang.c for 'null stream' in Google Groups. I was interested in exactly the same thing not too long ago and I found a few previous threads that seemed to cover it. Basically you have to.

Inserts data into the stream.
value
is short or int, then casts it to unsignedshort or unsignedint if ios_base::flags()& ios_base::basefield is ios_base::oct or ios_base::hex. After that, casts to long in any case and outputs as in (3). If value
is unsignedshort or unsignedint, casts to unsignedlong and outputs as in (3).*this << s
, where s
is a null-terminated character type string.sb
is a null pointer. If it is, executes setstate(badbit) and exits. Otherwise, extracts characters from the input sequence controlled by sb
and inserts them into *this until one of the following conditions are met:- end-of-file occurs on the input sequence;
- inserting in the output sequence fails (in which case the character to be inserted is not extracted);
- an exception occurs (in which case the exception is caught).
failbit
is set in exceptions(), rethrows the exception.[edit]Parameters
value | - | integer, floating-point, boolean, or pointer value to insert |
func | - | function to call |
sb | - | pointer to the streambuffer to read the data from |

[edit]Notes
C 2b 2b Ostream Dev Null Command
There are no overload for pointers to non-static member, pointers to volatile, or function pointers (other than the ones with signatures accepted by the (10-12) overloads). Attempting to output such objects invokes implicit conversion to bool, and, for any non-null pointer value, the value 1 is printed (unless boolalpha was set, in which case true is printed).
Character and character string arguments (e.g., of type char or constchar*) are handled by the non-member overloads of operator<<
. Attempting to output a character using the member function call syntax (e.g., std::cout.operator<<('c');) will call one of overloads (2-4) and output the numerical value. Attempting to output a character string using the member function call syntax will call overload (7) and print the pointer value instead.
