SNMPHOST Source Code

56. InitDevTable() allocates memory for retrieved device information.

57. Memory is allocated and descriptors initialized for the GetNext and Get encoded-

packet buffers.

58. GetHostDevices() retrieves device information.

59. DisplayHostDevices() prints it.

60. Buffer memory is deallocated, and SNMP_Close_() terminates communication with

the agent.
