+/* NAME
+/* master_ent 3
+/* SUMMARY
+/* Postfix master - config file access
+/* SYNOPSIS
+/* #include "master.h"
+/*
+/* void fset_master_ent(path)
+/* char *path;
+/*
+/* void set_master_ent()
+/*
+/* MASTER_SERV *get_master_ent()
+/*
+/* void end_master_ent()
+/*
+/* void print_master_ent(entry)
+/* MASTER_SERV *entry;
+/*
+/* void free_master_ent(entry)
+/* MASTER_SERV *entry;
+/* DESCRIPTION
+/* This module implements a simple programmatic interface
+/* for accessing Postfix master process configuration files.
+/*
+/* fset_master_ent() specifies the location of the master process
+/* configuration file. The pathname is copied.
+/*
+/* set_master_ent() opens the configuration file. It is an error
+/* to call this routine while the configuration file is still open.
+/* It is an error to open a configuration file without specifying
+/* its name to fset_master_ent().
+/*
+/* get_master_ent() reads the next entry from an open configuration
+/* file and returns the parsed result. A null result means the end
+/* of file was reached.
+/*
+/* print_master_ent() prints the specified service entry.
+/*
+/* end_master_ent() closes an open configuration file. It is an error
+/* to call this routine when the configuration file is not open.
+/*
+/* free_master_ent() destroys the memory used for a parsed configuration
+/* file entry.
+/* DIAGNOSTICS
+/* Panics: interface violations. Fatal errors: memory allocation
+/* failure.
