libpthread.a 는 정적라이브러리 인가요? 동적라이브러리 인가요?

Building the library as a statically linkable library
-----------------------------------------------------
 
General: PTW32_STATIC_LIB must be defined for both the library build and the
application build. The makefiles supplied and used by the following 'make'
command lines will define this for you.
 
MSVC (creates pthreadVCn.lib as a static link lib):
 
nmake clean VC-static
 
 
MinGW32 (creates libpthreadGCn.a as a static link lib):
 
make clean GC-static
 
 
Define PTW32_STATIC_LIB when building your application. Also, your
application must call a two non-portable routines to initialise the
some state on startup and cleanup before exit. One other routine needs
to be called to cleanup after any Win32 threads have called POSIX API
routines. See README.NONPORTABLE or the html reference manual pages for
details on these routines:
 
BOOL pthread_win32_process_attach_np (void);
BOOL pthread_win32_process_detach_np (void);
BOOL pthread_win32_thread_attach_np (void); // Currently a no-op
BOOL pthread_win32_thread_detach_np (void);
 
 
The tests makef iles have the same targets but only check that the
static library is statically linkable. They don't run the full
testsuite. To run the full testsuite, build the dlls and run the
dll test targets.

/*
 
 * When building the DLL code, you should define PTW32_BUILD so that
 
 * the variables/functions are exported correctly. When using the DLL,
 
 * do NOT define PTW32_BUILD, and then the variables/functions will
 
 * be imported correctly.
