evthread_lock_callbacks

This structure describes the interface a threading library uses for locking. It's used to tell evthread_set_lock_callbacks() how to use locking on this platform.

extern (C) nothrow

struct evthread_lock_callbacks {

int lock_api_version;

uint supported_locktypes;

ExternC!(void* function(uint locktype)) alloc;

ExternC!(void function(void* lock, uint locktype)) free;

ExternC!(int function(uint mode, void* lock)) lock;

alloc ExternC!(void* function(uint locktype)) alloc;: Function to allocate and initialize new lock of type 'locktype'. * Returns NULL on failure.
free ExternC!(void function(void* lock, uint locktype)) free;: Funtion to release all storage held in 'lock', which was created * with type 'locktype'.
lock ExternC!(int function(uint mode, void* lock)) lock;: Acquire an already-allocated lock at 'lock' with mode 'mode'. * Returns 0 on success, and nonzero on failure.
lock_api_version int lock_api_version;: The current version of the locking API. Set this to * EVTHREAD_LOCK_API_VERSION
supported_locktypes uint supported_locktypes;: Which kinds of locks does this version of the locking API support? A bitfield of EVTHREAD_LOCKTYPE_RECURSIVE and EVTHREAD_LOCKTYPE_READWRITE.
unlock ExternC!(int function(uint mode, void* lock)) unlock;: Release a lock at 'lock' using mode 'mode'. Returns 0 on success, * and nonzero on failure.
