NAME

       fmt_plusminus - write '+' or '-'

SYNTAX

       #include <fmt.h>

       size_t fmt_plusminus(char *dest,signed int source);

DESCRIPTION

       fmt_plusminus writes '-' to dest if source is negative, '+' if source is positive, nothing
       otherwise.  It returns the number of bytes written.

       fmt_plusminus does not append \0.

       If dest equals FMT_LEN (i.e. is zero), fmt_plusminus returns the number of bytes it  would
       have written.
