If something went wrong then return non-zero, preferably between 1 and 127.

This is termed the exit code of a process and in a shell becomes the "$?" value.

This allows you to do the following

Code:
if myprogram
then 
      echo all went well
else 
      echo bad things
fi

can it be bigger than 127?
thanks

snmp_set_quick_print - Set the value of$quick_printwithin the UCDSNMPlibrary

SYNOPSIS
bool snmp_set_quick_print (bool $quick_print) DESCRIPTION
Sets the value of $quick_print within the UCD SNMP library. When this is set (1), the SNMP library will return 'quick printed' values. This means that just the value will be printed. When $quick_print is not enabled (default) the UCD SNMP library prints extra information including the type of the value (i.e. IpAddress or OID). Additionally, if quick_print is not enabled, the library prints additional hex values for all strings of three characters or less. By default the UCD SNMP library returns verbose values, quick_print is used to return only the value. Currently strings are still returned with extra quotes, this will be corrected in a later release. PARAMETERS
o $quick_print - RETURN VALUES
No value is returned. EXAMPLES
Setting quick_print is often used when using the information returned rather than displaying it. Example #1 Using snmp_set_quick_print(3) <?php snmp_set_quick_print(0); $a = snmpget("127.0.0.1", "public", ".1.3.6.1.2.1.2.2.1.9.1"); echo "$a "; snmp_set_quick_print(1); $a = snmpget("127.0.0.1", "public", ".1.3.6.1.2.1.2.2.1.9.1"); echo "$a "; ?> The above example will output something similar to: SEE ALSO
