To permit checking the sources out on systems such as Windows with more restrictive file name requirements, rename the manpage source files to replace colons with underscrores. Use MANSRC.foo to point <bsd.man.mk> at the new source file names. Reviewed by: ivy Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D51794

|

.Ft using FILE_up = std::unique_ptr<FILE, fclose_deleter>;
|
|
.Sh DESCRIPTION
|
|
This class is a specialization of
|
|
.Vt std::unique_ptr
|
|
for stdio
|
|
.Vt FILE
|
|
objects.
|
|
When a
|
|
.Vt FILE
|
|
object managed by an instance of this class is disposed,
|
|
.Xr fclose 3
|
|
is invoked to dispose of the
|
|
.Vt FILE
|
|
object.
|
|
.Sh EXAMPLES
|
|
.Bd -literal -offset indent
|
|
freebsd::FILE_up fp(fopen("foo.txt", "w"));
|
|
if (!fp)
|
|
err(1, "fopen");
|
|
fprintf(fp.get(), "hello\n");
|
|
// `fp' is implicitly closed on destruction
