@ fGZip

Set of flags for gzip file support. See each flag description above.

#define NCBI_THROW(exception_class, err_code, message)

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

int32_t Int4

4-byte (32-bit) signed integer

uint32_t Uint4

4-byte (32-bit) unsigned integer

TFastMutexGuard CFastMutexGuard

...and backward compatibility
