| | | | | | | | | | | | | | | | | | | | | | * lib/windows-spawn.h (prepare_spawn): Add a second parameter. * lib/windows-spawn.c: Don't include xalloc.h. (quoted_arg_length, quoted_arg_string): New functions, extracted from prepare_spawn. (prepare_spawn): Use malloc instead of XNMALLOC. Allocate memory for all elements of *new_argv together. * modules/windows-spawn (Depends-on): Remove xalloc. Add malloc-posix. * lib/os2-spawn.h (prepare_spawn): Add a second parameter. * lib/os2-spawn.c: Don't include xalloc.h. (prepare_spawn): Use malloc instead of XNMALLOC. Allocate memory for all elements of *new_argv together. * lib/execute.c: Include xalloc.h. (execute): Check return value of prepare_spawn. Free the memory allocated by prepare_spawn. * modules/execute (Depends-on): Add xalloc-die. * lib/spawn-pipe.c: Include xalloc.h. (create_pipe): Check return value of prepare_spawn. Free the memory allocated by prepare_spawn. * modules/spawn-pipe (Depends-on): Add xalloc-die.
