#define __func__   DEBUG_ENTRY.name()

all vendors supply predefined preprocessor symbols to help identify their hardware/operating system/compiler, the following symbols will be used to bracket hardware/OS/compiler specific code:

Sun Sparc: __sun DEC Alpha: __alpha SGI Iris: __sgi HP Unix: __hpux Cray: __cray IA32: __i386 AMD64/EM64T: __amd64 UNIX: __unix (includes Linux) Linux: __linux MS Vis C: _MSC_VER Intel compiler: __ICC, __INTEL_COMPILER g++/icc/pathCC: __GNUC__ (also set by icc and pathCC!) g++: __GNUC_EXCL__ (excludes icc, pathCC)

NOTE: the user should NOT define these symbols at compile time. the Intel EM64T compiler does not set the __amd64 flag... on some UNIX systems only the preprocessor symbol "unix" is predefined (e.g. DEC alpha), on others only "__unix" (e.g. Cray), and on yet others both... This ensures "__unix" is always defined on all UNIX systems. on SGI IA64 systems, icc calls itself ecc... this is needed to discriminate between g++ and icc/pathCC/openCC/clang++

Enumeration Type Documentation

flag used as third parameter for open_data, indicates how data files are searched AS_DATA_ONLY: search only in the data directories, not in the current working directory (default) AS_DATA_OPTIONAL: same as AS_DATA_ONLY, except that the precense of the file is optional AS_DATA_LOCAL: search in data directories first, then in the current working directory AS_LOCAL_DATA: search in the current working directory first, then in the data directories AS_LOCAL_ONLY: search in the current working directory only versions with _TRY appended have the same meaning, except that they don't abort

set_NaN - set variable or array to SNaN

define routines for setting single and double precision signaling NaN The bit pattern for an SNaN is implementation defined, but this should work on most modern CPU's. The system definition is preferred, so in C++ this should be replaced by numeric_limits<TYPE>::signaling_NaN()
