193 The remaining arguments are optional.
194 The program's input comes from file INFILE (nil means `/dev/null').
195 Insert output in BUFFER before point; t means current buffer;
196 nil for BUFFER means discard it; 0 means discard and don't wait.
197 BUFFER can also have the form (REAL-BUFFER STDERR-FILE); in that case,
198 REAL-BUFFER says what to do with standard output, as above,
199 while STDERR-FILE says what to do with standard error in the child.
200 STDERR-FILE may be nil (discard standard error output),
201 t (mix it with ordinary output), or a file name string.
203 Fourth arg DISPLAY non-nil means redisplay buffer as output is inserted.
204 Remaining arguments are strings passed as command arguments to PROGRAM.
206 If executable PROGRAM can't be found as an executable, `call-process'
207 signals a Lisp error. `call-process' reports errors in execution of
208 the program only through its return and output.
210 If BUFFER is 0, `call-process' returns immediately with value nil.
211 Otherwise it waits for PROGRAM to terminate
212 and returns a numeric exit status or a signal description string.
213 If you quit, the process is killed with SIGINT, or SIGKILL if you quit again.
