equivalent of /dev/null, and the suffixes used by executable
files. This is simple, and helps people porting Emacs to other
operating systems.
* process.h (NULL_DEVICE): Give this a default value.
* process.c (Fstart_process): Pass EXEC_SUFFIXES to openp.
(Fprocess_send_eof): Use NULL_DEVICE instead of "/dev/null".
* callproc.c (Fcall_process): Pass EXEC_SUFFIXES to openp.
Use NULL_DEVICE instead of "/dev/null".
Lisp_Object, to smooth type-checking.
* callproc.c (init_callproc): Move the initialization of
Vprocess_environment to its own function.
(set_process_environment): This is that.
* emacs.c (main): Call set_process_environment earlier than
init_callproc.
for subprocesses when the buffer's default-directory is a handled
name.
* fileio.c (Funhandled_file_name_directory): New function.
(Qunhandled_file_name_directory): New file-name-handler operation.
(syms_of_fileio): Defsubr Sunhandled_file_name_directory, and
initialize and staticpro Qunhandled_file_name_directory.
* callproc.c (Fcall_process): Call Funhandled_file_name_directory
on the buffer's default directory. Do it earlier in the function
so there's less to GCPRO.
* process.c (create_process): Don't check the validity of the
buffer's default directory here...
(Fstart_process): Instead, do it here; if we call
Funhandled_file_name_directory here, there's less GCPROing to do.
* callproc.c (Fcall_process_region): Return the value returned by
Fcall_process.
first time the user quits, or SIGKILL if the user quits again.
#include "syssignal.h".
(call_process_kill): New function.
(call_process_cleanup): Send SIGINT to the subprocess, and then
arrange to call call_process_kill if the user quits while we wait
for it to terminate.
(Fcall_process, Fcall_process_region): Doc fix.
