Open
And finally, we can write a function to open the stream:
PHP_FUNCTION(example_open)
{
char *filename;
long filename_len;
php_stream *stream;
struct my_stream_data *data;
if (FAILURE == zend_parse_parameters(
ZEND_NUM_ARGS() TSRMLS_CC, "s", &filename,
&filename_len)) {
return;
}
data = emalloc(sizeof(struct my_stream_data));
data->filedes = open(filename, O_RDWR);
stream = php_stream_alloc(&my_ops, data, NULL, "r+");
php_stream_to_zval(stream, return_value);
}
