Init and Fini Usage Example

This example consists of three shared libraries lib1.sl, lib2.sl and lib3.sl. The lib1.sl depends on lib3.sl. The main program (a.out) depends on lib1.sl and lib2.sl. Each shared library has an init style initializer and a fini style terminator. The lib1.sl and lib2.sl uses linker options (+init and +fini) to specify the initializers and terminators and lib3.sl uses compiler pragmas.

C source for lib1.sl (file lib1.c):

lib1()

{

printf(“lib1\n”);

}

void

lib1_init()

{

printf(“lib1_init\n”);

}

void

lib1_fini()

{

printf(“lib1_fini\n”);

}

C source for lib2.sl (file lib2.c):

lib2()

{

printf(“lib2\n”);

}

void

lib2_init()

{

printf(“lib2_init\n”);

}

void

lib2_fini()

{

printf(“lib2_fini\n”);

}
