@struct sc_thread_context_t Structure for the locking function to use when using libopensc in a multi-threaded application.

Fields

ver: c_uint

the version number of this structure (0 for this version)

create_mutex: Option<unsafe extern "C" fn(arg1: *mut *mut c_void) -> c_int>

creates a mutex object

lock_mutex: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>

locks a mutex object (blocks until the lock has been acquired)

unlock_mutex: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>

unlocks a mutex object

destroy_mutex: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>

destroys a mutex object

thread_id: Option<unsafe extern "C" fn() -> c_ulong>

returns unique identifier for the thread (can be NULL)
