acl_db_file_exists_c

	status.i4.v = acl_db_file_exists_c(file_name.i1a.r [,options.u4.v]
					   [,actual_name.i1a.r]
					   [,max_return.i4.v])

	This routine determines whether or not an Accelerator Command Language
	(ACL) database script exists.  It searches the table ACL_DB_TABLE.

	file_name	null terminated file name
	[options]	read options
			(ACL_OPT_NONE -> no options selected (default),
			 ACL_OPT_DONT_CLOSE -> leave database connection
					       open upon exit (close later
					       with db_close))
	[actual_name]	null terminated actual file name
			(allow ACL_DB_FILE_NAME_LEN + 1 characters)
			(default is NULL)
	[max_return]	maximum number of characters to return for the
			actual name
			(default is 0)

	This function returns ACNET status values as follows:

	TRUE			file exists
	FALSE			file does not exist
	CLIB_MEMFAIL		failed in allocating dynamic memory
	otherwise		other ACNET format error code

	This function requires the following include files:

	ul_acl_h:acl_h, acnet_errors_h
