<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 <curl/mprintf.h> file. Then all the normal names like
|
||
|
|
printf, fprintf, sprintf etc will use the curl-functions
|
||
|
|
instead.
|
||
|

|
||
|

|
||
|
|
<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.
