XXIII. Direct IO functions
Direct I/O Functions
PHP supports the direct io functions as described in the Posix Standard (Section 6) for performing I/O functions at a lower level than the C-Language stream I/O functions (fopen, fread,..).
Installation
To get these functions to work, you have to configure PHP with --enable-dio.
- Obsah
- dio_open — Opens a new filename with specified permissions of flags and creation permissions of mode
- dio_read — Reads n bytes from fd and returns them, if n is not specified, reads 1k block
- dio_write — Writes data to fd with optional truncation at length
- dio_truncate — Truncates file descriptor fd to offset bytes
- dio_stat — Gets stat information about the file descriptor fd
- dio_seek — Seeks to pos on fd from whence
- dio_fcntl — Performs a c library fcntl on fd
- dio_close — Closes the file descriptor given by fd
