NAME

libsmi - library to access SMI management information

DESCRIPTION

This library contains functions that allow access to SMI management information stored in repositories that are managed by libsmi, currently directories containing SMIv1/v2 and SMIng MIB module files.

The libsmi API is defined in smi.h. Functions are documented in smi_config(3), smi_module(3), smi_node(3), smi_type(3), and smi_macro(3).

The purpose of libsmi is to separate the weird parsing and handling of MIB modules from management applications. MIB modules conforming to SMIv1, SMIv2 and SMIng - a new language for management information, developed originally at the Technical University of Braunschweig, Germany - can be handled by libsmi.

EXAMPLE

#include <stdio.h>
#include <string.h>
#include <smi.h>
int main(int argc, char *argv[])
{


    SmiNode *smiNode;


    SmiModule *smiModule;


    int i, oidlen, first = 1;


    const char *modules[] = {
	"SNMPv2-SMI", "SNMPv2-TC", "SNMPv2-CONF",
	"SNMPv2-MIB", "IF-MIB", NULL


    };


    if (argc != 2) {
	fprintf(stderr, "Usage: smisubtree oid0);
	exit(1);


    }


    smiInit(NULL);


    for (i = 0; modules[i]; i++) {
	fprintf(stderr, "loading MIB module '%s'0, modules[i]);
	(void) smiLoadModule(modules[i]);


    }


    for((smiNode = smiGetNode(NULL, argv[1])) &&
	    (oidlen = smiNode->oidlen);
	smiNode && (first || smiNode->oidlen > oidlen);
	smiNode = smiGetNextNode(smiNode, SMI_NODEKIND_ANY),
	    first = 0) {
	printf("%*s%-32s0,
	       (smiNode->oidlen - oidlen + 1) * 2, " ",
	       smiNode->name ? smiNode->name : "<?>");


    };


    exit(0);
}
