| * libc_init_static.c |
| * |
| * This function is called for static executables, i.e. those that |
| * dont depend on shared libraries and are directly started by the |
| * Linux kernel. |
| * |
| * It takes the raw data block set up by the ELF loader |
| * in the kernel and parses it. |
| * |
| * The arguments are: |
| * elfdata -- The ELF loader data block; usually from the stack. |
| * Basically a pointer to argc. |
| * |
| * onexit -- Function to call on exit, can be NULL. |
| * |
| * slingshot -- Address of the program's main function |
| * |
| * structors -- Table of constructor functions arrays that must |
| * be called before the slingshot. |
| * |
| * It is called from the assembly fragment found in |
| * arch-$ARCH/bionic/crtbegin_static.S |

| * Several Linux ABIs don't pass the onexit pointer, and the ones that |
