void enable_sigfpe

(

void

)

Enable SIGFPE delivery

Referenced by main().

std::string prepend_filename	(	const std::string &	path,
		const std::string &	prefix
	)

prepend file at the leaf of path with prefix /path/to/file becomes /path/to/prefixfile

std::string cut_path

(

const std::string &

path

)

strip off the path information of a file e.g. cut_path( "test/bla/lall.fits") -> "lall.fits"

std::string remove_extension	(	const string &	path,
		const string &	ext
	)

return a copy of path with the filename extension ext (after last .) stripped off e.g. remove_extension( "lall.fits", ".fits" ) -> "lall"

Referenced by copy_org_models(), fit_initial_dist(), main(), and refit_models().

std::string remove_extension

(

const string &

path

)

return a copy of path with the filename extension (after last .) stripped off

std::string mktmpfile

(

std::ofstream &

of

)

return a unique file name in /tmp. calls libc mktemp().

bool readNextLineFromStream	(	std::istream &	in,
		std::string &	buff
	)

Try to read the next available line from an input filestream. Returns false if no more lines can be read. Removes leading whitespace and all characters following a '#' indicating a comment.

void write_cmd_line	(	std::ostream &	os,
		const string &	version,
		int	argc,
		char *	argv[],
		const bool	nodate
	)

write the full command line and the program version to a stream.

Referenced by main(), mkimage_dither_files(), mkimage_single_files(), and TableHeader::write_header().

void clamp_window	(	const int	value,
		const int	low,
		const int	high,
		const int	delta,
		int *	vlow,
		int *	vhigh
	)

Clamp a value such that it is always between low and high with a margin of delta. Used for sliding a window across a frame.

bool comp_string_size	(	const std::string &	str1,
		const std::string &	str2
	)

function to compare string lengths in vectors. Used compute the width of the columns in the table header
