std::put_money

template <class moneyT>/*unspecified*/ put_money (const moneyT& mon, bool intl = false);

Put monetary value

Inserts the representation of mon as a monetary value into the output stream it is applied to.

Internally, the function accesses the output sequence by first constructing an object of type basic_ostream::sentry. Then (if evaluating the sentry object is true), it calls money_put::put (using the stream's selected locale) to perform both the formatting and the insertion operations, adjusting the stream's internal state flags accordingly. Finally, it destroys the sentry object before returning.

This manipulator is declared in header <iomanip>.

Parameters

mon: Monetary value.
moneyT shall be either long double or a basic_string instantiation.
intl: true for international representations, false otherwise.
This is used internally to instantiate the proper moneypunct class.

Return Value

Unspecified. This function should only be used as a stream manipulator (see example).

Errors are signaled by modifying the stream's internal state flags:

flag	error
`eofbit`	-
`failbit`	The function failed to format `mon` (it may also be set if the construction of `sentry` failed).
`badbit`	Either the insertion on the stream failed, or some other error happened (such as when this function catches an exception thrown by an internal operation). When set, the integrity of the stream may have been affected.

Multiple flags may be set by a single operation.

If the operation sets an internal state flag on the stream that was registered using its member exceptions, the function throws an exception of type ios_base::failure.

Example

// put_money manipulator example
#include <iostream>     // std::cout
#include <iomanip>      // std::put_money

int main ()
{
  std::cout << "Price:" << std::put_money(10.50L) << '\n';
  return 0;
}

Data races

Modifies the stream object where it is inserted.
Concurrent access to the same stream object may cause data races, except for the standard stream objects (cout, cerr, clog, wcout, wcerr and wclog) when these are synchronized with stdio (in this case, no data races are initiated, although no guarantees are given on the order in which characters from multiple threads are inserted).

Exception safety

Basic guarantee: if an exception is thrown, the object is in a valid state.
It throws an exception of member type failure if the resulting error state flag is not goodbit and member exceptions was set to throw for that state.
Any exception thrown by an internal operation is caught and handled by the function, setting badbit. If badbit was set on the last call to exceptions, the function rethrows the caught exception.
