class	kjb::Pthread_mutex
	dynamically allocated mutex: unlock before you destroy it! More...
struct	kjb::Pthread_locked_mutex
	same as Pthread_mutex, but starts off in "locked" state. More...
class	kjb::Mutex_lock
	simple RAII class to grab and release a mutex More...
class	kjb::Pthread_attr
	RAII class to manage an object of type kjb_pthread_attr_t. More...
class	kjb::Fftw_convolution_2d
	A class for performing 2d convolution using the FFTW library. More...

Functions

	test whether a Work_buffer object is the last handle to its memory More...

Detailed Description

This group contains classes that support multi-threaded programs, at a low level (like mutexes) and at a high level (like partially thread-safe, paralleized classes for fast convolution).

Function Documentation

bool kjb::work_buffer_is_unique ( const Fftw_convolution_2d::Work_buffer &  b )

inline

test whether a Work_buffer object is the last handle to its memory

This is a utility function useful for reasons described in Destroying a Work_buffer
