stream_set_write_buffer Sets file buffering on the given stream &reftitle.description; intstream_set_write_buffer resourcestream intbuffer Sets the buffering for write operations on the given stream to buffer bytes. Output using fwrite is normally buffered at 8K. This means that if there are two processes wanting to write to the same output stream (a file), each is paused after 8K of data to allow the other to write. &reftitle.parameters; stream The file pointer. buffer The number of bytes to buffer. If buffer is 0 then write operations are unbuffered. This ensures that all writes with fwrite are completed before other processes are allowed to write to that output stream. &reftitle.returnvalues; Returns 0 on success, or EOF if the request cannot be honored. &reftitle.examples; The following example demonstrates how to use stream_set_write_buffer to create an unbuffered stream. ]]> &reftitle.seealso; fopen fwrite
