Read data from the file.
The buffer that the data will be written to.
The offset within the buffer where writing will start.
An integer specifying the number of bytes to read.
An integer specifying where to begin reading from in the file. If position is null, data will be read from the current file position.
Promise resolving to the new length of the buffer
Read data from the file.
The buffer that the data will be written to.
The offset within the buffer where writing will start.
An integer specifying the number of bytes to read.
Optionalposition: numberAn integer specifying where to begin reading from in the file. If position is null, data will be read from the current file position.
Write buffer to the file. Note that it is unsafe to use fs.write multiple times on the same file without waiting for the callback.
Uint8Array containing the data to write to the file.
Offset in the buffer to start reading data from.
The amount of bytes to write to the file.
Offset from the beginning of the file where this data should be written. If position is null, the data will be written at the current position.
Promise resolving to the new length of the buffer
Write buffer to the file. Note that it is unsafe to use fs.writeSync multiple times on the same file without waiting for it to return.
Uint8Array containing the data to write to the file.
Offset in the buffer to start reading data from.
The amount of bytes to write to the file.
Optionalposition: numberOffset from the beginning of the file where this data should be written. If position is null, the data will be written at the current position.
Get the current file position.
