Treat BITS as just OCTET STRING.
Example API's for processing bits from char* variable,
Call this function by passing *val* from set_handler,
/*
* bits -- set val
* pos -- which bit you want to read from set val
*/
int bit_get(const unsigned char *bits, int pos) {
unsigned int mask;
int i;
mask = 0x80;
for (i=0; i < (pos % 8); i++)
mask = mask >> 1;
return (((mask & bits[(int)(pos / 8)]) == mask) ? 1 : 0);
}
Call this function by passing *ret_val* from get_handler,
/*
* bits -- ret value from get_handler from function
* pos -- which bit you want to set
*/
void bit_set(unsigned char *bits, int pos) {
unsigned char mask;
int i;
mask = 0x80;
for (i = 0; i < (pos % 8); i++)
mask = mask >> 1;
bits[pos / 8] = bits[pos / 8] | mask;
return;
}
Example snmpset command,
Snmpset column.<index> x 28
OR
snmpset column.<index> b proxyServer,registrarServer

Subject: How to convert BITS data into OCTET String
Hi,
We have a column in the table that have datatype of BITS. After
compilation of the MIB file, it is converted into a character array. I
found some information in the RFC# 3416/3417 regarding the conversion
but could not understand well how to convert BITS field into the octet
string. Following is the BITS field we are using:
SYNTAX BITS {
other(0),
userAgent(1),
proxyServer(2),
redirectServer(3),
registrarServer(4)
}
Now, I have to set bit 2 (proxyServer) and 4 (registrarServer) into the
octet string.
Please guide me how the conversion would actually take place.
I suppose that numbering would be:
8 7 6 5 4 3 2 1
- - X - X - - -
If these bits would be set then index 0 of the octet string should be
equal to: 0x28.
Is that correct?
Kind Regards,
-Abhishek
