STRFMON(3)             FreeBSD 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,
         ...);

     ssize_t
     strfmon_l(char * restrict s, size_t maxsize, locale_t loc,
         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 strfmon_l() function does the same as strfmon() but takes an explicit
     locale rather than using the current locale.

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

     The strfmon_l() function returns the same values as strfmon().

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'').
     The strfmon_l() function conforms to IEEE Std 1003.1-2008 (``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 standards' text.

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