.SH 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.

||
|
|
.RS
|
||
|
|
.TP
|
||
|
|
.B curl_mprintf()
|
||
|
|
Normal printf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_mfprintf()
|
||
|
|
Normal fprintf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_msprintf()
|
||
|
|
Normal sprintf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_msnprintf()
|
||
|
|
snprintf() clone. Many systems don't have this. It is just like \fBsprintf\fP
|
||
|
|
but with an extra argument after the buffer that specifies the length of the
|
||
|
|
target buffer.
|
||
|
|
.TP
|
||
|
|
.B curl_mvprintf()
|
||
|
|
Normal vprintf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_mvfprintf()
|
||
|
|
Normal vfprintf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_mvsprintf()
|
||
|
|
Normal vsprintf() clone.
|
||
|
|
.TP
|
||
|
|
.B curl_mvsnprintf()
|
||
|
|
vsnprintf() clone. Many systems don't have this. It is just like
|
||
|
|
\fBvsprintf\fP but with an extra argument after the buffer that specifies the
|
||
|
|
length of the target buffer.
|
||
|
|
.TP
|
||
|
|
.B curl_maprintf()
|
||
|
|
Like printf() but returns the output string as a malloc()ed string. The
|
||
|
|
returned string must be free()ed by the receiver.
|
||
|
|
.TP
|
||
|
|
.B curl_mvaprintf()
|
||
|
|
Like curl_maprintf() but takes a va_list pointer argument instead of a
|
||
|
|
variable amount of arguments.
|
||
|
|
.RE
|
||
|
|
.SH AVAILABILITY
|
||
|
|
These functions will be removed from the public libcurl API in the future. Do
|
||
|
|
not use them in any new programs or projects.
|
||
|
|
.SH RETURN VALUE
|
||
|
|
The \fBcurl_maprintf\fP and \fBcurl_mvaprintf\fP 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.
