No more than .Fa maxsize bytes are placed into the array. .Pp The format string is composed of zero or more directives: ordinary characters (not .Cm % ) , 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 .Cm % character. After the .Cm % , the following appear in sequence: .Bl -bullet .It Zero or more of the following flags: .Bl -tag -width "XXX" .It Cm = Ns Ar f A .Sq Cm = character followed by another character .Ar f which is used as the numeric fill character. .It Cm ^ Do not use grouping characters, regardless of the current locale default. .It Cm + Represent positive values by prefixing them with a positive sign, and negative values by prefixing them with a negative sign. This is the default. .It Cm \&( Enclose negative values in parentheses. .It Cm \&! Do not include a currency symbol in the output. .It Cm \- Left justify the result. Only valid when a field width is specified. .El .It An optional minimum field width as a decimal number. By default, there is no minimum width. .It A .Sq Cm # sign followed by a decimal number specifying the maximum expected number of digits after the radix character. .It A .Sq Cm \&. character followed by a decimal number specifying the number of digits after the radix character. .It One of the following conversion specifiers: .Bl -tag -width "XXX" .It Cm i The .Vt double argument is formatted as an international monetary amount. .It Cm n The .Vt double argument is formatted as a national monetary amount. .It Cm % A .Sq Li % character is written. .El .El .Sh RETURN VALUES If the total number of resulting bytes including the terminating .Dv NULL byte is not more than .Fa maxsize , .Fn strfmon returns the number of bytes placed into the array pointed to by .Fa s , not including the terminating .Dv NULL byte. Otherwise, \-1 is returned, the contents of the array are indeterminate, and .Va errno is set to indicate the error. .Sh ERRORS The .Fn strfmon function will fail if: .Bl -tag -width Er .It Bq Er E2BIG Conversion stopped due to lack of space in the buffer. .It Bq Er EINVAL The format string is invalid. .It Bq Er ENOMEM Not enough memory for temporary buffers. .El .Sh SEE ALSO .Xr localeconv 3 .Sh STANDARDS The .Fn strfmon function conforms to .St -p1003.1-2001 . .Sh AUTHORS .An -nosplit The .Fn strfmon function was implemented by .An Alexey Zelkin Aq phantom@FreeBSD.org . .Pp This manual page was written by .An Jeroen Ruigrok van der Werven Aq asmodai@FreeBSD.org based on the standard's text. .Sh BUGS The .Fn strfmon function does not correctly handle multibyte characters in the .Fa format argument.
