Declaration

func CFStringCreateWithFormatAndArguments(_ alloc: CFAllocator!, _ formatOptions: CFDictionary!, _ format: CFString!, _ arguments: CVaListPointer) -> CFString!

Parameters

• alloc:

  The allocator to use to allocate memory for the new string. Pass NULL or Kcfallocatordefault to use the current default allocator.

• formatOptions:

  A CFDictionary object containing formatting options for the string (such as the thousand-separator character, which is dependent on locale). Currently, these options are an unimplemented feature.

• format:

  The formatted string with printf-style specifiers. For information on supported specifiers, see TP40004265.

• arguments:

  The variable argument list of values to be inserted into the formatted string contained in format.

Return Value

An immutable string, or NULL if there was a problem creating the object. Ownership follows the The Create Rule.

Discussion

The programming interface for variable argument lists (va_list, va_start, va_end, and so forth) is declared in the standard C header file stdarg.h.
