DPDK device class interface.
This file describes the interface of the device class abstraction layer.
A device class defines the type of function a device will be used for e.g.: Ethernet adapter (eth), cryptographic co-processor (crypto), etc.
Definition in file rte_class.h.
#define RTE_REGISTER_CLASS | ( | nm, | |
cls | |||
) |
Helper for Class registration. The constructor has lower priority than Bus constructors. The constructor has higher priority than PMD constructors.
Definition at line 111 of file rte_class.h.
Class comparison function.
cls | Class under test. |
data | Data to compare against. |

Double linked list of classes
struct rte_class* rte_class_find | ( | const struct rte_class * | start, |
rte_class_cmp_t | cmp, | ||
const void * | data | ||
) |
Class iterator to find a particular class.
This function compares each registered class to find one that matches the data passed as parameter.
If the comparison function returns zero this function will stop iterating over any more classes. To continue a search the class of a previous search can be passed via the start parameter.
start | Starting point for the iteration. |
cmp | Comparison function. |
data | Data to pass to comparison function. |
struct rte_class* rte_class_find_by_name | ( | const char * | name | ) |
Find the registered class for a given name.
void rte_class_register | ( | struct rte_class * | cls | ) |
Register a Class handle.
cls | A pointer to a rte_class structure describing the class to be registered. |
