* exec/trace.c (process_vm_readv, process_vm_writev): New function pointers. Attempt to load them on recent Android systems when `exec' was not linked with a sufficiently up-to-date libc. (read_memory, user_copy): Always use process_vm_readv and process_vm_writev if available. (handle_openat): Write trailing NULL byte of filename to user buffer. (exec_init): Attempt to dlsym process_vm_readv and process_vm_writev.
This directory holds the source code to a library used to replace the `execve' and `execveat' system calls, used by the Android port of Emacs to start executables without intervention from the system.
