* editor -- fork editor to edit some text file
|
|
*
|
|
* Usage:
|
|
* i = editor(file, prompt);
|
|
* char *file, *prompt;
|
|
* int i;
|
|
*
|
|
* The editor() routine is used to fork the user's favorite editor.
|
|
* There is assumed to be an environment variable named "EDITOR" whose
|
|
* value is the name of the favored editor. If the EDITOR parameter is
|
|
* missing, some default (see DEFAULTED below) is assumed. The runp()
|
|
* routine is then used to find this editor on the searchlist specified
|
|
* by the PATH variable (or the default path). "file" is the name of
|
|
* the file to be edited and "prompt" is a string (of any length) which
|
|
* will be printed in a such a way that the user can see it at least at
|
|
* the start of the editing session. editor() returns the value of the
|
|
* runp() call.
