stream_set_write_buffer Sets write 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. &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 another value 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
