stream_set_read_buffer Set read file buffering on the given stream &reftitle.description; intstream_set_read_buffer resourcestream intbuffer Sets the read buffer. It's the equivalent of stream_set_write_buffer, but for read operations. &reftitle.parameters; stream The file pointer. buffer The number of bytes to buffer. If buffer is 0 then read operations are unbuffered. This ensures that all reads with fread are completed before other processes are allowed to read from that input stream. &reftitle.returnvalues; Returns 0 on success, or EOF if the request cannot be honored. &reftitle.seealso; stream_set_write_buffer
