zero a buffer in io_passfd so valgrind does not complain when we pass it to a syscall (which did not use the uninitialized parts anyway)

.TH fmt_strm 3
|
|
.SH NAME
|
|
fmt_strm \- write multiple ASCII strings
|
|
.SH SYNTAX
|
|
.B #include <fmt.h>
|
|
|
|
size_t \fBfmt_strm\fP(char *\fIdest\fR,const char *\fIsource\fR, ...);
|
|
.SH DESCRIPTION
|
|
fmt_strm copies all leading nonzero bytes from \fIsource\fR and
|
|
following
|
|
function arguments to \fIdest\fR and returns the number of bytes it
|
|
copied.
|
|
|
|
fmt_strm does not append \\0.
|
|
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_str returns the number
|
|
of bytes it would have written, i.e. the number of leading nonzero bytes
|
|
of \fIsource\fR and following function arguments.
