function public ustring.h System UnicodeString

Description

Appends result of given format string and its arguments to end of UnicodeString.

Use cat_sprintf to append to the value of the UnicodeString object, given a standard C++ format specifier. Pass the values to any arguments in the format specifier as additional parameters following the format parameter.

For example, the following code:

UnicodeString Salutation = "Mr."
UnicodeString s = "";
s.cat_sprintf("Dear %s ", Salutation);
s.cat_sprintf("%s,", "Smith");

results in an UnicodeString object with the value

Dear Mr. Smith,

This method returns a reference to the UnicodeString object (*this) with the resulting value.

Warning: The value returned by UnicodeString.c_str() under OS X and iOS is char16_t* while the cat_sprintf function expects wchar_t*.
