What Is __Libc_Init_Array at Linda Rowlands blog

What Is __Libc_Init_Array. The.preinit_array and.init_array sections contain arrays of pointers to functions that will be called on initialization. Calling __libc_init_array has to be done after initializing the data and bss sections, because otherwise you would overwrite the things that the __libc_init_array function sets up. If you need to support c and c++, the first thing you'll need to do is to add a call to __libc_init_array right before you call (or jump to) main. C start up so something must. All we need to do is call __libc_init_array prior to main in our reset_handler, and we are good to go. Newlib then offers a function, __libc_init_array which iterates over the array and invokes every constructor. In this post i'm going to cover how some of the aspects of c start up and mess around with the.init_array and.fini_array sections to show how they work. You can find out more about it by reading the source code. The location of the.bss section is identified during initialization, and the memory is typically set to 0 with memset. As the startup code is often written in assembly, newlib provides the functions __libc_init_array and __libc_fini_array to run.
