/* We can't use libc's (f)printf because it would reenter in replace_malloc,
|
|
* So use a custom and simplified version.
|
|
* Only %p and %z are supported.
|
|
* /!\ This function used a fixed-size internal buffer. The caller is
|
|
* expected to not use a format string that may overflow.
|
|
* The aFd argument is a file descriptor on UNIX and a native win32 file
|
|
* handle on Windows (from CreateFile). We can't use the windows POSIX
|
|
* APIs is that they don't support O_APPEND in a multi-process-safe way,
|
|
* while CreateFile does.
