References DescriptorIsValid(), error(), m_stream, and StreamIsValid().

◆ GetDescriptor()

int NativeFile::GetDescriptor ( ) const

overridevirtual

Get underlying OS file descriptor for this file, or kInvalidDescriptor.

If the descriptor is valid, then it may be used directly for I/O However, the File may also perform it's own buffering, so avoid using this if it is not necessary, or use Flush() appropriately.

Returns: a valid file descriptor for this file or kInvalidDescriptor

◆ GetFileSpec()

Status NativeFile::GetFileSpec ( FileSpec & file_spec ) const

overridevirtual

Get the file specification for this file, if possible.

Parameters

[out] file_spec the file specification.

Returns: ENOTSUP, success, or another error.

References lldb_private::FileSpec::Clear(), error(), GetDescriptor(), IsValid(), PATH_MAX, and lldb_private::FileSpec::SetFile().

◆ GetOptions()

Expected< File::OpenOptions > NativeFile::GetOptions ( ) const

overridevirtual

Return the OpenOptions for this file.

Some options like eOpenOptionDontFollowSymlinks only make sense when a file is being opened (or not at all) and may not be preserved for this method. But any valid File should return either eOpenOptionReadOnly, eOpenOptionWriteOnly or eOpenOptionReadWrite here.

Returns: OpenOptions flags for this file, or an error.

Reimplemented from lldb_private::File.

Definition at line 255 of file File.cpp.

References m_options.

◆ GetStream()

FILE * NativeFile::GetStream ( )

overridevirtual

Get the underlying libc stream for this file, or NULL.

Not all valid files will have a FILE* stream. This should only be used if absolutely necessary, such as to interact with 3rd party libraries that need FILE* streams.

Returns: a valid stream or NULL;

Definition at line 280 of file File.cpp.

◆ GetWaitableHandle()

IOObject::WaitableHandle NativeFile::GetWaitableHandle ( )

overridevirtual

Get a handle that can be used for OS polling interfaces, such as WaitForMultipleObjects, select, or epoll.

This may return IOObject::kInvalidHandleValue if none is available. This will generally be the same as the file descriptor, this function is not interchangeable with GetDescriptor(). A WaitableHandle must only be used for polling, not actual I/O.

Returns: a valid handle or IOObject::kInvalidHandleValue

◆ Read() [1/2]

Status NativeFile::Read	(	void *	buf,
		size_t &	num_bytes
	)

overridevirtual

Read bytes from a file from the current file position into buf.

NOTE: This function is NOT thread safe. Use the read function that takes an "off_t &offset" to ensure correct operation in multi- threaded environments.

Parameters

[in,out] num_bytes Pass in the size of buf. Read will pass out the number of bytes read. Zero bytes read with no error indicates EOF.

Returns: success, ENOTSUP, or another error.

◆ Read() [2/2]

Status NativeFile::Read	(	void *	dst,
		size_t &	num_bytes,
		off_t &	offset
	)

overridevirtual

Read bytes from a file from the specified file offset.

NOTE: This function is thread safe in that clients manager their own file position markers and reads on other threads won't mess up the current read.

Parameters

[in]	dst	A buffer where to put the bytes that are read.
[in,out]	num_bytes	The number of bytes to read from the current file position which gets modified with the number of bytes that were read.
[in,out]	offset	The offset within the file from which to read num_bytes bytes. This offset gets incremented by the number of bytes that were read.

Returns: An error object that indicates success or the reason for failure.

◆ SeekFromCurrent()

off_t NativeFile::SeekFromCurrent	(	off_t	offset,
		Status *	error_ptr = `nullptr`
	)

overridevirtual

Seek to an offset relative to the current file position.

NOTE: This function is NOT thread safe, other threads that access this object might also change the current file position. For thread safe reads and writes see the following functions:

See also: File::Read (void *, size_t, off_t &); File::Write (const void *, size_t, off_t &)

Parameters

[in]	offset	The offset to seek to within the file relative to the current file position.
[in]	error_ptr	A pointer to a lldb_private::Status object that will be filled in if non-nullptr.

Returns: The resulting seek offset, or -1 on error.

◆ SeekFromEnd()

off_t NativeFile::SeekFromEnd	(	off_t	offset,
		Status *	error_ptr = `nullptr`
	)

overridevirtual

Seek to an offset relative to the end of the file.

NOTE: This function is NOT thread safe, other threads that access this object might also change the current file position. For thread safe reads and writes see the following functions:

See also: File::Read (void *, size_t, off_t &); File::Write (const void *, size_t, off_t &)

Parameters

[in,out]	offset	The offset to seek to within the file relative to the end of the file which gets filled in with the resulting absolute file offset.
[in]	error_ptr	A pointer to a lldb_private::Status object that will be filled in if non-nullptr.

Returns: The resulting seek offset, or -1 on error.

		Status *	error_ptr = `nullptr`
	)

overridevirtual

Seek to an offset relative to the beginning of the file.

Parameters

[in,out] num_bytes Pass in the size of buf. Write will pass out the number of bytes written. Write will attempt write the full number of bytes and will not return early except on error.

◆ Write() [2/2]

Status NativeFile::Write	(	const void *	src,
		size_t &	num_bytes,
		off_t &	offset
	)

overridevirtual

Write bytes to a file at the specified file offset.

NOTE: This function is thread safe in that clients manager their own file position markers, though clients will need to implement their own locking externally to avoid multiple people writing to the file at the same time.

Parameters

[in]	src	A buffer containing the bytes to write.
[in,out]	num_bytes	The number of bytes to write to the file at offset offset. num_bytes gets modified with the number of bytes that were read.
[in,out]	offset	The offset within the file at which to write num_bytes bytes. This offset gets incremented by the number of bytes that were written.

Returns: An error object that indicates success or the reason for failure.
