# prcs-callback(1)

Callback script for Ediff support in prcs.el

## NAME

prcs-callback - Callback script for Ediff support in prcs.el

## SYNOPSIS

**(setq prcs-callback-program prcs-callback )**

## DESCRIPTION

This manual page documents briefly the **prcs-merge-command**, script. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

**prcs-callback** is associated with *prcs.el*.  When called with some number of arguments, this script:

```
    1. Prints a special magic token on a line by itself.
    2. Prints the number of args on a line by itself.
    3. Prints each of the args in turn on their own lines.
    4. Waits for input.
    5. Reads a line (should be an integer), and exits with
       that status.
```

It is used by *prcs.el* as a value for $PRCS\_DIFF\_COMMAND or $PRCS\_MERGE\_COMMAND. The token is used to identify its execution in a general comint buffer.
