Function Documentation

read_parameter_file()

void read_parameter_file	(	char *	fname,
		int *	ShowBacktrace,
		double *	MaxMemSizePerNode
	)

This function parses the parameterfile in a simple way. Each paramater is defined by a keyword (‘tag’), and can be either of type douple, int, or character string. The routine makes sure that each parameter appears exactly once in the parameterfile, otherwise error messages are produced that complain about the missing parameters.
