HH\Lib\File\leaky_temporary_file
Creates a new temporary file, without automatic cleanup
namespace HH\Lib\File;
function leaky_temporary_file(
string $prefix = 'hack-leakytmp-',
string $suffix = '',
): CloseableReadWriteHandle;
File\temporary_file() is strongly recommended instead.
- If the prefix starts with
., it is interpreted relative to the current working directory. - If the prefix statis with
/, it is treated as an absolute path. - Otherwise, it is created in the system temporary directory.
Regardless of the kind of prefix, the parent directory must exist.
A suffix can optionally be provided; this is useful when you need a
particular filename extension; for example,
File\temporary_file('foo', '.txt') may create /tmp/foo123456.txt.
The temporary file:
- will be a new file (i.e.
O_CREAT | O_EXCL) - be owned by the current user
- be created with mode 0600
- will not be automatically deleted
