Problems with Constants (9)

	Change	Effect
1	The value of constant DNS_MAX_IP4_REVERSE_NAME_BUFFER_LENGTH has been changed from (DNS_MAX_IP4_REVERSE_NAME_LENGTH + 1) to (IP4_ADDRESS_STRING_LENGTH+15).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant DNS_MAX_IP4_REVERSE_NAME_LENGTH has been changed from (IP4_ADDRESS_STRING_LENGTH+1+sizeof(DNS_IP4_REVERSE_DOMAIN_STRING_A)) to (IP4_ADDRESS_STRING_LENGTH+15).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant DNS_MAX_IP6_REVERSE_NAME_BUFFER_LENGTH has been changed from (DNS_MAX_IP6_REVERSE_NAME_LENGTH + 1) to (75).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant DNS_MAX_IP6_REVERSE_NAME_LENGTH has been changed from (64+sizeof(DNS_IP6_REVERSE_DOMAIN_STRING_A)) to (75).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant IP4_ADDRESS_STRING_LENGTH has been changed from (15) to (16).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant IP6_ADDRESS_STRING_BUFFER_LENGTH has been changed from (48) to (65).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant IP6_ADDRESS_STRING_LENGTH has been changed from (47) to (65).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
