Function Documentation

int assemble_command	(	int	argc,
		char *	argv[],
		char *	command
	)

Create a string containing the command used to run the program.

It can be very useful for the program's output file to have a comment line that contains the command used to run the program. This function assembles that command into a string from the argc and argv parameters so it can be added to the output file.

Parameters

[in]	argc	Argument count (parameter passed to main)
[in]	argv	Argument vector (parameter passed to main)
[out]	command	String containing the command line

Returns

Number of elements on the command line

Here is the caller graph for this function:

void check_filename	(	char *	in,
		char *	out
	)

Make sure that the filename is not too long.

If the input string is not to big, copy it to the output string. Otherwise, exit with an error message. This function is used to check that the user input filename is not too long.

Parameters

[in]	in	Input string = the user input filename (or base filename)
[out]	out	Output string = the input string, if not too long

double* create_array	(	int	N,

Also initialize the array to all 0.

Parameters

[in]	N	Number of elements in array
[in]	string	String containing a description of the array (for debugging purposes)

Returns

Pointer to the new array
