SYNOPSIS

       #include <curl/mprintf.h>

       int curl_mprintf(const char *format, ...);
       int curl_mfprintf(FILE *fd, const char *format, ...);
       int curl_msprintf(char *buffer, const char *format, ...);
       int curl_msnprintf(char *buffer, size_t maxlength, const char *format, ...);
       int curl_mvprintf(const char *format, va_list args);
       int curl_mvfprintf(FILE *fd, const char *format, va_list args);
       int curl_mvsprintf(char *buffer, const char *format, va_list args);
       int curl_mvsnprintf(char *buffer, size_t maxlength, const char *format, va_list args);
       char *curl_maprintf(const char *format, ...);
       char *curl_mvaprintf(const char *format, va_list args);

DESCRIPTION

       These  are  all functions that produce 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.

              curl_mprintf()
                     Normal printf() clone.

              curl_mfprintf()
                     Normal fprintf() clone.

              curl_msprintf()
                     Normal sprintf() clone.

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

              curl_mvprintf()
                     Normal vprintf() clone.

              curl_mvfprintf()
                     Normal vfprintf() clone.

              curl_mvsprintf()
                     Normal vsprintf() clone.

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

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

              curl_mvaprintf()
                     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 <curl/mprintf.h> 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.

RETURN VALUE

       The  curl_maprintf  and curl_mvaprintf functions return a pointer to a newly allocated string, or NULL if
       it failed.

       All other functions return the number of characters they actually outputted.
