NAME

       rtf_get_version - Returns the version of the library

SYNOPSIS

       #include <rtfilter.h>

       size_t rtf_get_version(char *string, size_t len, unsigned int line);

DESCRIPTION

       This  function  fills  in string the version of the library if line is 0. It fills at most
       len character in string including the terminating null byte (' '). If  the  implementation
       of library depends on other non-standard libraries, it will returns the version of them in
       subsequent lines (line > 0). If there is no more dependency, nothing is copied  on  string
       and 0 is returned by the function.

RETURN VALUE

       Returns the number of characters copied on string.
