Main function (entry point) for the NCBI application.

const TCgiEntries & GetEntries(void) const

Get a set of entries(decoded) received from the client.

@ eDS_Default

Try standard log file (app.name + ".log") in /log/, use stderr on failure.

static void DumpState()

Dump many of the most common OpenGL states.

static double StringToDouble(const CTempStringEx str, TStringToNumFlags flags=0)

Convert string to double.

Magic spell ;-) needed for some weird compilers... very empiric.

Defines classes: CDirEntry, CFile, CDir, CSymLink, CMemoryFile, CFileUtil, CFileLock,...
