(

int

argc,

const char

* argv[])

virtual void Init(void)

Initialize the application.

virtual int Run(void)

Run the application.

virtual void Exit(void)

Cleanup on application exit.

static bool ReadImageInfo(const string &file, size_t *width, size_t *height, size_t *depth, EType *type)

read just the image information

CNcbiOstrstreamToString class helps convert CNcbiOstrstream to a string Sample usage:

static unsigned char depth[2 *(256+1+29)+1]

virtual const CArgs & GetArgs(void) const

Get parsed command line arguments.

int AppMain(int argc, const char *const *argv, const char *const *envp=0, EAppDiagStream diag=eDS_Default, const char *conf=NcbiEmptyCStr, const string &name=NcbiEmptyString)

Main function (entry point) for the NCBI application.

virtual void SetupArgDescriptions(CArgDescriptions *arg_desc)

Setup the command line argument descriptions.

const CNcbiArguments & GetArguments(void) const

Get the application's cached unprocessed command-line arguments.

@ fBinary

Open as binary file; for eInputFile, eOutputFile, eIOFile.

@ eInputFile

Name of file (must exist and be readable)

#define LOG_POST(message)

This macro is deprecated and it's strongly recomended to move in all projects (except tests) to macro...

void SetDiagStream(CNcbiOstream *os, bool quick_flush=true, FDiagCleanup cleanup=0, void *cleanup_data=0, const string &stream_name="")

Set diagnostic stream.

void Error(CExceptionArgs_Base &args)

#define NCBI_THROW(exception_class, err_code, message)

Generic macro to throw an exception, given the exception class, error code and message string.

IO_PREFIX::istream CNcbiIstream

Portable alias for istream.

int main(int argc, const char *argv[])

Defines the CNcbiApplication and CAppException classes for creating NCBI applications.

Defines command line argument related classes.

Defines unified interface to application:

Process information in the NCBI Registry, including working with configuration files.

Defines: CTimeFormat - storage class for time format.
