Does this question is not worth answering???
Any omments on this design is welcome. Is there anything you would revise? If so, how?
How to modfiy the .c file init_XXX(void) function?
Below is my new problem:
My mib file is ok(MG-soft checked).my mib had added in the mib library rightly(snmp.conf:mibs +ALL),and snmptranslate -IR -Tp got my mib tree rightly.
I use command 'mib2c uit' and chose net-snmp code style,the next 1,and 1,I got the uit.c,uit.h files.
My uit.c file and some modifies.

I put the files in net-snmp source code ./agent/mibgroup/ directory.
I want to static load my MIB module use the command
./configure --with-mib-modules="uit";make;make install
when I had done the installation,I cannot load my uit module，I use command 'snmpwalk -v2c -c public localhost' and 'snmpget'but get nothing i really need about my mib.
Who can tell me where I was wrong here about my mib?
TIA
Alex
