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

NAME
     strfmon -- convert monetary value to string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <monetary.h>

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

DESCRIPTION
     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
	      character.

	 ^    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
	 width.

     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.

RETURN VALUES
     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.

ERRORS
     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.

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

AUTHORS
     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.

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