DESCRIPTION
       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.

              ccuurrllmmpprriinnttff(())
                     Normal printf() clone.

              ccuurrllmmffpprriinnttff(())
                     Normal fprintf() clone.

              ccuurrllmmsspprriinnttff(())
                     Normal sprintf() clone.

              ccuurrllmmssnnpprriinnttff(())
                     snprintf() clone. Many systems don't  have  this.  It  is
                     just  like  sspprriinnttff  but with an extra argument after the
                     buffer that specifies the length of the target buffer.

              ccuurrllmmvvpprriinnttff(())
                     Normal vprintf() clone.

              ccuurrllmmvvffpprriinnttff(())
                     Normal vfprintf() clone.

              ccuurrllmmvvsspprriinnttff(())
                     Normal vsprintf() clone.

              ccuurrllmmvvssnnpprriinnttff(())
                     vsnprintf() clone.  Many systems don't have this.  It  is
                     just  like  vvsspprriinnttff but with an extra argument after the
                     buffer that specifies the length of the target buffer.

              ccuurrllmmaapprriinnttff(())
                     Like printf() but returns the output  string  as  a  mal-
                     loc()ed  string.  The returned string must be free()ed by
                     the receiver.

              ccuurrllmmvvaapprriinnttff(())
                     Like curlmaprintf() but takes a valist pointer argument
                     instead of a variable amount of arguments.

       To  easily  use  all these cloned functions instead of the normal ones,
       #define MPRINTFREPLACE before you include the   file.
       Then  all  the  normal names like printf, fprintf, sprintf etc will use
       the curl-functions instead.

AVAILABILITY       These function will be removed from the public libcurl API  in  a  near
       future.  They  will  instead  be made "available" by source code access
       only, and then as curlx-prefixed functions. See  lib/README.curlx  for
       further details.

RREETTUURRNN VVAALLUUEE
       The  ccuurrllmmaapprriinnttff  and  ccuurrllmmvvaapprriinnttff functions return a pointer to a
       newly allocated string, or NULL it it failed.

       All other functions return the number of character they  actually  out-
       puted.
