The program's input comes from file INFILE (nil means `/dev/null').
Insert output in BUFFER before point; t means current buffer; nil for BUFFER
Insert output in DESTINATION before point; t means current buffer; nil for DESTINATION

FILE is a file name string, means that it should be written to that file
\(if the file already exists it is overwritten).
BUFFER can also have the form (REAL-BUFFER STDERR-FILE); in that case,
DESTINATION can also have the form (REAL-BUFFER STDERR-FILE); in that case,
REAL-BUFFER says what to do with standard output, as above,
while STDERR-FILE says what to do with standard error in the child.
STDERR-FILE may be nil (discard standard error output),

If BUFFER is 0, `call-process' returns immediately with value nil.
If DESTINATION is 0, `call-process' returns immediately with value nil.
Otherwise it waits for PROGRAM to terminate
