#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.failsafe for obsolete or buggy systems to assure that the POSIX symbol __linux is defined on SGI IA64 systems, icc calls itself ecc... this is needed to discriminate between g++ and icc/pathCC/openCC/clang++

Enumeration Type Documentation

enum access_scheme

flag used as third parameter for open_data, indicates how data files are searched AS_DEFAULT: use default behavior: AS_DATA_ONLY for reading, AS_LOCAL_ONLY for writing AS_DATA_ONLY: search only in the data directories, not in the current working directory AS_DATA_OPTIONAL: same as AS_DATA_ONLY, except that the precense of the file is optional 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 AS_SILENT_TRY: same as AS_LOCAL_ONLY_TRY, but does not write to ioQQQ in trace mode

void set_NaN ( sys_float & x )

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()
