设置 UCD SNMP 库中 quick_print 的值。当此值被设置（1），SNMP
库将返回‘快速打印’值。这意味着将只打印值。当
quick_print 被禁用时（此为默认情况），UCD SNMP
库将打印出额外信息，包括值的类型（如 IpAddress 或
OID）。此外，如果 quick_print 是禁用的，UCD SNMP
库将为所有字符串额外打印出三个或更少字符的十六进制值。
</p>
<p class="para">
当需要使用返回的信息而不是显示它时，经常会用到设置 quick_print。

第一个打印出来的值可能时：&#039;Timeticks: (0) 0:00:00.00&#039;，然而当设置了
quick_print 之后，只是打印 &#039;0:00:00.00&#039;。

<p class="para">
默认情况下 UCD SNMP 库返回冗余的值，而 quick_print
则用来只返回值。

现时，字符串依然返回额外的引号，这将会在后续发行版中更正。

<span class="function"><strong>snmp_set_quick_print()</strong></span> 仅在使用了 UCD SNMP
库时才可用。当使用 Windows SNMP 库时，此函数不可用。
