/* This file contains GAHP protocol-related code that's shared between
 * the gridmanager and the c-gahp. Eventually, the parsing and unparsing
 * code should be here, but the way the two daemons read the commands off
 * the wire is too different. For now, we just share the data structure
 * for holding the parsed array of strings.
 */

/* Users of GahpArgs should not manipulate the class data members directly.
 * Changing the object should only be done via the member functions.
 * If argc is 0, then the value of argv is undefined. If argc > 0, then
 * argv[0] through argv[argc-1] point to valid null-terminated strings. If
 * a NULL is passed to add_arg(), it will be ignored. argv may be resized
 * or freed by add_arg() and reset(), so users should not copy the pointer
 * and expect it to be valid after these calls.
