DESCRIPTION

27       These  are  all  functions  that  produce  output according to a format
28       string and given arguments. These are mostly clones of  the  well-known
29       C-style  functions  and  there  will  be no detailed explanation of all
30       available formatting rules and usage here.
31
32       See this table for notable exceptions.
33
34              curl_mprintf()
35                     Normal printf() clone.
36
37              curl_mfprintf()
38                     Normal fprintf() clone.
39
40              curl_msprintf()
41                     Normal sprintf() clone.
42
43              curl_msnprintf()
44                     snprintf() clone. Many systems don't  have  this.  It  is
45                     just  like  sprintf  but with an extra argument after the
46                     buffer that specifies the length of the target buffer.
47
48              curl_mvprintf()
49                     Normal vprintf() clone.
50
51              curl_mvfprintf()
52                     Normal vfprintf() clone.
53
54              curl_mvsprintf()
55                     Normal vsprintf() clone.
56
57              curl_mvsnprintf()
58                     vsnprintf() clone.  Many systems don't have this.  It  is
59                     just  like  vsprintf but with an extra argument after the
60                     buffer that specifies the length of the target buffer.
61
62              curl_maprintf()
63                     Like printf() but returns the output  string  as  a  mal‐
64                     loc()ed  string.  The returned string must be free()ed by
65                     the receiver.
66
67              curl_mvaprintf()
68                     Like curl_maprintf() but takes a va_list pointer argument
69                     instead of a variable amount of arguments.
70
71       To  easily  use  all these cloned functions instead of the normal ones,
72       #define _MPRINTF_REPLACE before you include the <curl/mprintf.h>  file.
73       Then  all  the  normal names like printf, fprintf, sprintf etc will use
74       the curl-functions instead.
75

AVAILABILITY

77       These function will be removed from the public libcurl API  in  a  near
78       future.  They  will  instead  be made "available" by source code access
79       only, and then as curlx_-prefixed functions. See  lib/README.curlx  for
80       further details.
81

RETURN VALUE

83       The  curl_maprintf  and  curl_mvaprintf functions return a pointer to a
84       newly allocated string, or NULL if it failed.
85
86       All other functions return the number of characters they actually  out‐
87       putted.
