BloombergLP::bdls::FdStreamBuf::FdStreamBuf

Create a FdStreamBuf associated with the specified fileDescriptor that refers to an already opened file or device, and specify writableFlag which, if true, indicates that fileDescriptor is writable, otherwise it is not. The optionally specified willCloseOnResetFlag, if true, indicates that fileDescriptor is to be closed the next time this object is reset, cleared or destroyed, or if false the file descriptor is to be left open. Optionally specify a binaryModeFlag which is ignored on Unix; if false on Windows, it indicates that ` `s are to be translated to and from `\r ` sequences on the device. Optionally specify a basicAllocator` used to supply memory. If `basicAllocator is 0, the currently installed default allocator is used. The supplied file descriptor, if valid, should remain open until the next call to either reset or the destructor. Note that if FilesystemUtil::k_INVALID_FD is passed to fileDescriptor, no file descriptor is to be associated with this object. Also note that the state of the fileDescriptor is unchanged by this call (i.e., there is no implicit seek).
