<H2>DESCRIPTION</H2><PRE>
       These are all functions that produces output according  to
       a  format  string  and  given  arguments. These are mostly
       clones of the well-known C-style functions and there  will
       be  no  detailed  explanation  of all available formatting
       rules and usage here.

       See this table for notable exceptions.

              <B>curl_mprintf()</B>
                     Normal printf() clone.

              <B>curl_mfprintf()</B>
                     Normal fprinf() clone.

              <B>curl_msprintf()</B>
                     Normal sprintf() clone.

              <B>curl_msnprintf()</B>
                     snprintf() clone. Many  systems  don't  have
                     this.  It  is  just like <B>sprintf</B> but with an
                     extra argument after the buffer that  speci-
                     fies the length of the target buffer.

              <B>curl_mvprintf()</B>
                     Normal vprintf() clone.

              <B>curl_mvfprintf()</B>
                     Normal vfprintf() clone.
                     Normal vsprintf() clone.

              <B>curl_mvsnprintf()</B>
                     vsnprintf()  clone.  Many systems don't have
                     this. It is just like <B>vsprintf</B> but  with  an
                     extra  argument after the buffer that speci-
                     fies the length of the target buffer.

              <B>curl_maprintf()</B>
                     Like printf() but returns the output  string
                     as  a malloc()ed string. The returned string
                     must be free()ed by the receiver.

              <B>curl_mvaprintf()</B>
                     Like curl_maprintf()  but  takes  a  va_list
                     pointer   argument  instead  of  a  variable
                     amount of arguments.

       To easily use all these cloned functions  instead  of  the
       normal  ones,  #define _MPRINTF_REPLACE before you include
       the &lt;curl/mprintf.h&gt; file. Then all the normal names  like
       printf,  fprintf,  sprintf etc will use the curl-functions
       instead.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       The <B>curl_maprintf</B> and <B>curl_mvaprintf</B>  functions  return  a
       pointer to a newly allocated string, or NULL it it failed.

       All other functions return the number  of  character  they
       actually outputed.
