/*
 * Definition of getaction() routine which does keyword parsing
 *
 * Operation: A character string containing the ascii cmd to be
 * parsed is passed in along with an array of structures.
 * The 1st struct element is a recognizable cmd string, the second
 * is the minimum number of characters from the start of this string
 * to succeed on a match. For example, { "offline", 3, ONLINE }
 * will match "off", "offli", "offline", but not "of" nor "offlinebarf"
 * The third element is the {usually but not necessarily unique}
 * integer to return on a successful match. Note: compares are cAsE insensitive.
 *
 * To change, extend or use this utility, just add or remove appropriate
 * lines in the structure initializer below and in the #define	s for the
 * return values.
 *
 *                              N O T E
 * Do not change the minimum number of characters to produce
 * a match as someone may be building scripts that use this
 * feature.
