Extension to enable ioctl() call support on PHP. Still in development as a Proof-Of-Concept.
phpize
./configure --enable-ioctl
make && make install
You will need to add extension=ioctl.so into your php.ini file.
function ioctl(resource fd, int request, string data, boolean is_ptr) : int
- fd: File descriptor resource, open with fopen()
- request: Request call, see ioctl(2)
- data: Buffer to be passed to ioctl() call, this function does not do any bound checking as its impossible to determine which kind of data is required by the driver. This is left as responsability to PHP script developer.
- is_ptr: Whether the ioctl call expects a value (is_ptr = false) or a pointer (is_ptr = true) in which case the value will be the first bytes of the string that fit into a pointer data type (4 bytes for 32 bit systems, 8 bytes for 64 bit systems) and the pointer will be pointing to the string data itself. If the ioctl() call returns some value into a struct pointer, the PHP developer should supply a string with enough size to fit the data in.
- FALSE: the ioctl() call has failed.
- any other value: the integer result of the ioctl() call.
