Using Header Files, Data

Structures, and Defines

This section describes Manager Services data definitions used in conjunction with the

library functions.

Header Files

Table 4-1 summarizes the Manager Services header files you need to include in your

manager source code. Although Manager Services provides additional header files,

these are the only ones you need to explicitly include. The other header files are

included as needed by those listed in Table 4-1

Typedefs

Table 4-2 summarizes the typedefs defined by Manager Services. Many of these are

used in the packet-handling structures defined by Manager Services and described in the

Packet-Handling Structures on page 4-2.

C File

Name

System File

Name File Description

asn1.h asn1h Defines tags, data types, and macros for handling the ASN.1

subset used by SNMP and defines the structure used to

describe an OID (OBJ_ID_T)

buffer.h bufferh Defines the structure describing encoded-packet buffers

(EBUFFER_T) and prototypes for related library functions

buildpkt.h buildpkh Defines prototypes for the library functions used to construct

request and trap packets and bind variable bindings to them

localio.h localioh Defines data structures and macros for handling undecoded

ASN.1 information

objectid.h objectih Defines entry points into library routines that manage OIDs

snmp.h snmph Includes snmpdefs.h

snmpdefs.h snmpdefh Defines the packet structure (SNMP_PKT_T) and prototypes

for related library functions

snmpstat.h snmpstah Defines the structure (SNMP_STATS_T) that holds statistics

describing packet decoding
