Namespaces
namespace	nidas::util
	General utility classes. nidas::util contains classes of general utility, like Socket, Thread, etc. The classes use only the standard Unix system libraries and libstdc++, and have no dependency on other external packages such as an XML parser, or a logging package.
namespace	nidas
	Root namespace for the NCAR In-Situ Data Acquisition Software.

Functions
std::string	nidas::util::replaceBackslashSequences (const std::string &str)
	Utility function for replacing backslash sequences in a string.
std::string	nidas::util::addBackslashSequences (const std::string &str)
	Utility function for substituting backslash sequences back into a string.
void	nidas::util::trimString (std::string &str)
	Utility to remove white space characters (matching isspace()) from end of string.
void	nidas::util::replaceCharsIn (std::string &in, const std::string &pat, const std::string &rep)
	Replace all occurences of pat in string in with rep.
std::string	nidas::util::replaceChars (const std::string &in, const std::string &pat, const std::string &rep)
std::string	nidas::util::svnStatus (const std::string &path)
	Run "svn status -v --depth empty" on a path and return a concatentated string of revision + flags, where flags are the first 8 characters.
float	nidas::util::dirFromUV (float u, float v)
	Calculate wind direction in degrees from U and V wind components, or if U and V are both zero return NAN as wind direction is undefined.
void	nidas::util::derive_uv_from_spd_dir (float &u, float &v, float &spd, float &dir)
	Normalize dir, then derive u and v from spd and direction.
void	nidas::util::derive_spd_dir_from_uv (float &spd, float &dir, float &u, float &v)
	Derive speed and direction from wind components u, v.
