Function Documentation

void announce_progress	(	int	now,
		int	total
	)

Indicates progress by printing the percentage of now/total.

A message is only printed if it has changed since now-1/total. The output is followed by a carriage return, not a newline.

Definition at line 195 of file cxxutils.cc.

void announce_progress	(	double	now,
		double	last,
		double	total
	)

Indicates progress by printing the percentage of now/total.

A message is only printed if it has changed since last/total. The output is followed by a carriage return, not a newline.

Definition at line 196 of file cxxutils.cc.

void end_announce_progress ( )

This function should be called after a sequence of announce_progress() calls has finished.

Definition at line 197 of file cxxutils.cc.

void announce ( const std::string & name )

Prints a banner containing name. Useful for displaying program names.

void module_startup	(	const std::string &	name,
		int	argc,
		const char **	argv,
		int	argc_expected,
		const std::string &	argv_expected
	)

Prints a banner containing name and checks if argc==argc_expected. If not, a usage description is given and the program is terminated.

unsigned int healpix_repcount ( int npix ) [inline]

Returns an appropriate FITS repetition count for a map with npix pixels.
