RTLD_NODELETE: 在dlclose()期间不卸载库,并且在以后使用dlopen()重新加载库时不初始化库中的静态变量。这个flag不是POSIX-2001标准。RTLD_NOLOAD: 不加载库。可用于测试库是否已加载(dlopen()返回NULL说明未加载,否则说明已加载),也可用于改变已加载库的flag,如:先前加载库的flag为RTLD_LOCAL,用dlopen(RTLD_NOL...

RTLD_LOCAL is the default; the RTLD_GLOBAL flag is not supported. RTLD_NODELETE is the default. It prevents static data from being initialized again on a subsequentdlcloseanddlopenof the same library. RTLD_NOLOAD tests to see if a program is resident. If the program is resident, the handl...
Describe the solution you'd like dlopen everything with RTLD_NODELETE. dlclose is anyway not completely safe under certain circumstances, the standard does not require it to do anything and is elsewhere implemented as a no-op. Describe alternatives you've considered ...
