The initget function provides a level of control over the next user-input function call. The initget function establishes various options for use by the next entsel, nentsel, nentselp, or getxxx function (except getstring, getvar, and getenv). This function accepts two arguments, bits and string, both of which are optional. The bits argument specifies one or more control bits that enable or disable certain input values to the next user-input function call. The string argument can specify keywords that the next user-input function call will recognize.
The control bits and keywords established by initget apply only to the next user-input function call. They are discarded after that call. The application doesn't have to call initget a second time to clear special conditions.
