类型参数名称
intargc
const char **argv
1754  offset等于0
1759  如果argv[0][2]且非是数字则返回:KDB return codes from a command or internal kdb function
1762  如果argc小于2则返回:KDB_ARGCOUNT
1765  nextarg等于1
1766  diag等于kdbgetaddrarg - This function is responsible for parsing an* address-expression and returning the value of the expression,* symbol name, and offset to the caller
1767  如果diag则返回:diag
1770  如果nextarg大于argc则返回:KDB_ARGCOUNT
