Macro Definition Documentation

MIB_RESOURCE

#define MIB_RESOURCE	(		name,
			handler,
			... )

Value:

  snmp_mib_resource_t name = { \
    NULL, \
    { \
      .data = { __VA_ARGS__ }, \
      .length = (sizeof((uint32_t[]){ __VA_ARGS__ }) / sizeof(uint32_t)) \
    }, \
    handler \
  };

Declare a MIB resource.

Parameters

name	A name for the MIB resource
handler	The handler function for this resource
...	The OID (comma-separated)

Definition at line 79 of file snmp-api.h.

OID

#define OID	(		name,
			... )

Value:

  static snmp_oid_t name = { \
    .data = { __VA_ARGS__ }, \
    .length = (sizeof((uint32_t[]){ __VA_ARGS__ }) / sizeof(uint32_t)) \
  };

Initializes statically an oid with the "null" terminator.

Remarks

This should be used inside handlers when declaring an oid

Parameters

name	A name for the oid
...	The Oid (comma-separeted)

void snmp_api_set_string	(	snmp_varbind_t *	varbind,
		snmp_oid_t *	oid,
		char *	string )

Function to set a varbind with a string.

This function should be used inside a handler to set the varbind correctly

Parameters

snmp_api_set_time_ticks()

void snmp_api_set_time_ticks	(	snmp_varbind_t *	varbind,
		snmp_oid_t *	oid,
		uint32_t	integer )

Function to set a varbind with a time tick.

This function should be used inside a handler to set the varbind correctly

Parameters
