long print	(	FILE *	out,
		int	ident = `0`
	)

prints element load to the file

The function prints element load data to the opened text file given by the parameter out. It is used in the mechprep preprocessor.

Parameters:

	out	- pointer to the opened text file
	ident	- number of spaces printed on the beginning of each new line except of last

Return values:

	0	- on success
	1	- unknown type of load is required

long read_prep	(	XFILE *	in,
		long	lc,
		long *	slc = `NULL`
	)

reads element load from the preprocessor file

The function reads element load data from the opened text file given by the parameter in. It is used in the mechprep preprocessor.

Parameters:

	in	- pointer to the opened text file
	lc	- total number of load cases
	slc	- pointer to array with number of subloadcases for individual load cases, defalut value is NULL

Return values:

	0	- on success
	1	- wrong load case id
	2	- unknown type of load is required
	3	- unknown load indicator is required
