libsmi(3)						SMI Management Information Library						 libsmi(3)

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, cur-
       rently 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 at the Technical University of Braunschweig, Germany - can be
       handled by libsmi.

       NOTE: SMIng support in the current release of libsmi is neither stable nor representing the work done in the IETF SMING working	group.	It
       is based research efforts at TU Braunschweig and within the IRTF in 1999-2000.

EXAMPLE

       #include <stdio.h>
       #include <string.h>
       #include <smi.h>

       int main(int argc, char *argv[])
       {
	   SmiNode *smiNode;
	   int oidlen, first = 1;

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

	   smiInit(NULL);

	   for((smiNode = smiGetNode(NULL, argv[1])) &&
		   (oidlen = smiNode->oidlen);
	       smiNode && (first || smiNode->oidlen > oidlen);
	       smiNode = smiGetNextNode(smiNode, SMI_NODEKIND_ANY),
		   first = 0) {

	       printf("%*s%-32s
",
		      (smiNode->oidlen - oidlen + 1) * 2, " ",
		      smiNode->name);

	   };

	   exit(0);
       }

SYNOPSIS

       #include <time.h>
       #include <smi.h>

       SmiModule *smiGetModule(char *module);

       SmiModule *smiGetFirstModule();

       SmiNode *smiGetModuleIdentityNode(SmiModule *smiModulePtr);

       SmiImport *smiGetNextImport(SmiImport *smiImportPtr);

       int smiIsImported(SmiModule *smiModulePtr, SmiModule *importedModulePtr, char *importedName);

       SmiRevision *smiGetFirstRevision(SmiModule *smiModulePtr);

       SmiRevision *smiGetNextRevision(SmiRevision *smiRevisionPtr);

       typedef struct SmiModule {
	   SmiIdentifier       name;
	   char 	       *path;
	   char 	       *organization;
	   char 	       *contactinfo;

       typedef struct SmiRevision {
	   time_t	       date;
	   char 	       *description;
       } SmiRevision;

	   SmiIdentifier       module;
	   SmiIdentifier       name;
       } SmiImport;

DESCRIPTION

       These functions retrieve various meta information on MIB modules. Other functions to retrieve the definitions within  a	module	are  docu-
       mented in smi_type(3), smi_node(3), and smi_macro(3).

       The smiGetModule() function retrieves a struct SmiModule that represents the SMI module named module. Elements not available or not present
       for this module contain NULL. If the module is not found, smiGetModule() returns NULL.

       The smiGetFirstModule() and smiGetNextModule() functions are used to iteratively retrieve struct SmiModules of all known modules.   smiGet-
       FirstModule() returns the first known module.  Subsequent calls to smiGetNextModule() return the following ones.  If there are no more mod-
       ules NULL is returned.

       The smiGetModuleIdentityNode() function retrieves a struct SmiNode that represents the node that is used to  identify  the  containing  MIB
       module  specified  by  smiModulePtr.  If there is no such identity node, i.e. if this is not an SMIv2 or SMIng module converted from SMIv2,
       smiGetModuleIdentityNode() returns NULL.

       The smiGetFirstImport() and smiGetNextImport() functions are used to iteratively retrieve struct SmiImports of  a  given  module.   smiGet-
       FirstImport() returns the first identifier imported by the module specified by smiModulePtr.  Subsequent calls to smiGetNextImport() return
       the following ones.  If there are no more imported identifiers NULL is returned.

       The smiIsImported() function returns a positive value if the identifier importedName defined in the module specified  by  importedModulePtr
       is imported in the module specified by smiModulePtr, or zero otherwise.

       The  smiGetFirstRevision()  and	smiGetNextRevision()  functions  are  used  to iteratively retrieve struct SmiRevisions of a given module.
       smiGetFirstRevision() returns the first (that is most recent) revision information of the  module  specified  by  smiModulePtr.	Subsequent
       calls to smiGetNextRevision() return the revision after (timely before) that one. If there are no more revisions NULL is returned.
