Transform - information about a transform connection
This data structure describes a connection between your transform
program and a transform daemon. It is returned by the RequestTransform function,
and is input to the ReleaseTransform function.
typedef struct {
const char* class_name; /* name of transformer class (63 bytes maximum) */
const int fd; /* connection to transform daemon */
} Transform;
The fields in this structure are:
- class_name
- The name of the transform and class in the format: transformname[_transformclass]. This value must match the name of a transform entry in the transform configuration file (aopxfd.conf). The format of class_name is: transformname[_transformclass].
- fd
- A UNIX file descriptor that is used to send input and receive output from the transform daemon.
