/* NAME
/* postconf_misc 3
/* SUMMARY
/* miscellaneous low-level code
/* SYNOPSIS
/* #include <postconf.h>
/*
/* void pcf_set_config_dir()
/*
/* const char *pcf_get_main_path()
/*
/* const char *pcf_get_master_path()
/* DESCRIPTION
/* pcf_set_config_dir() forcibly overrides the var_config_dir
/* parameter setting with the value from the environment or
/* with the default pathname, and updates the mail parameter
/* dictionary.
/*
/* pcf_get_main_path() and pcf_get_master_path() return a
/* pointer to a cached main.cf or master.cf full pathname,
/* based on the current var_config_dir setting. The functions
/* call pcf_set_config_dir() when no full pathname is cached.
/* DIAGNOSTICS
/* Problems are reported to the standard error stream.
/* LICENSE
/* .ad
