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.

AVAILABILITY

       These  functions  will  be  removed from the public libcurl API in the future. Do not use them in any new
       programs or projects.

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.
