@return   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 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: 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. An optional minimum field width as a decimal number.
By default, there is no minimum width. A ' \# '
sign followed by a decimal number specifying the maximum
expected number of digits after the radix character. A ' . '
character followed by a decimal number specifying the number
the number of digits after the radix character. 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.

Examples:
@code
#include <string.h>
#include <stdio.h>
#include <monetary.h>
int main()
{
    char buf[50];
    strfmon(buf, sizeof(buf), "[%^=*#6n] [%=*#6i]",1234.567, 1234.567);
    printf("%s
",buf);
}

@endcode
 Output
@code
[ **1234.57] [ **1234.57]
