Jump to headingFileHandle.write<TBuffer extends Uint8Array>(buffer: TBuffer,offset?: number | null,length?: number | null,position?: number | null,): Promise<{ bytesWritten: number; buffer: TBuffer; }>Write buffer to the file.
The promise is fulfilled with an object containing two properties:
It is unsafe to use filehandle.write() multiple times on the same file
without waiting for the promise to be fulfilled (or rejected). For this
scenario, use filehandle.createWriteStream().
On Linux, positional writes do not work when the file is opened in append mode. The kernel ignores the position argument and always appends the data to the end of the file.
Type Parameters Jump to heading
Jump to headingTBuffer extends Uint8ArrayParameters Jump to heading
Jump to headingbuffer: TBufferJump to headingoffset: number | nullThe start position from within buffer where the data to write begins.
Jump to headinglength: number | null = buffer.byteLength - offsetThe number of bytes from buffer to write.
Jump to headingposition: number | null = 'null'The offset from the beginning of the file where the data from buffer should be written. If position is not a number, the data will be written at the current
position. See the POSIX pwrite(2) documentation for more detail.
