NetBSD 6.1.5 - man page for strfmon (netbsd section 3)

STRFMON(3)			   BSD Library Functions Manual 		       STRFMON(3)

     strfmon -- convert monetary value to string

     Standard C Library (libc, -lc)

     #include <monetary.h>

     strfmon(char * restrict s, size_t maxsize, const char * restrict format, ...);

     The strfmon() function places characters into the array pointed to by s as controlled by the
     string pointed to by format.  No more than maxsize bytes are placed into the array.

     The format string is composed of zero or more directives: ordinary characters (not %), which
     are copied unchanged to the output stream; and conversion specifications, each of which
     results in fetching zero or more subsequent arguments.  Each conversion specification is
     introduced by the % character.  After the %, the following appear in sequence:

     o	 Zero or more of the following flags:

	 =f   A '=' character followed by another character f which is used as the numeric fill

	 ^    Do not use grouping characters, regardless of the current locale default.

	 +    Represent positive values by prefixing them with a positive sign, and negative val-
	      ues by prefixing them with a negative sign.  This is the default.

	 (    Enclose negative values in parentheses.

	 !    Do not include a currency symbol in the output.

	 -    Left justify the result.	Only valid when a field width is specified.

     o	 An optional minimum field width as a decimal number.  By default, there is no minimum

     o	 A '#' sign followed by a decimal number specifying the maximum expected number of digits
	 after the radix character.

     o	 A '.' character followed by a decimal number specifying the number of digits after the
	 radix character.

     o	 One of the following conversion specifiers:

	 i    The double argument is formatted as an international monetary amount.

	 n    The double argument is formatted as a national monetary amount.

	 %    A '%' character is written.

     If the total number of resulting bytes including the terminating NULL byte is not more than
     maxsize, strfmon() returns the number of bytes placed into the array pointed to by s, not
     including the terminating NULL byte.  Otherwise, -1 is returned, the contents of the array
     are indeterminate, and errno is set to indicate the error.

     The strfmon() function will fail if:

     [E2BIG]		Conversion stopped due to lack of space in the buffer.

     [EINVAL]		The format string is invalid.

     [ENOMEM]		Not enough memory for temporary buffers.


     The strfmon() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

     The strfmon() function was implemented by Alexey Zelkin <phantom@FreeBSD.org>.

     This manual page was written by Jeroen Ruigrok van der Werven <asmodai@FreeBSD.org> based on
     the standard's text.

     The strfmon() function does not correctly handle multibyte characters in the format argu-
