Parameters my_gsk_handle (Input) Indicates one of the following handles: v The handle for the secure session. (my_session_handle) v The handle for the SSL environment. (my_env_handle) bufID (Input) Indicates one of the following operations: v GSK_KEYRING_FILE (201) - buffer points to the name of the certificate store file to be used for the secure session or SSL environment. Authority to the certificate store file will be checked on the gsk_environment_init() API or the gsk_secure_soc_init() API. v GSK_KEYRING_PW (202) - buffer points to the password for the certificate store file to be used for the secure session or SSL environment. v GSK_KEYRING_LABEL (203) - buffer points to the certificate label associated with the certificate in the certificate store to be used for the secure session or SSL environment. v GSK_OS400_APPLICATION_ID (6999) - buffer points to the application identifier to be used for the SSL environment. v GSK_V2_CIPHER_SPECS (205) - buffer points to the list of SSL Version 2 ciphers to be used for the secure session or the SSL environment. v GSK_V3_CIPHER_SPECS (206) - buffer points to the list of SSL Version 3/TLS Version 1 ciphers to be used for the secure session or the SSL environment. buffer (Input) A pointer to the information to be used for the secure session or the SSL environment. The data in the buffer is assumed to be represented in the CCSID (coded character set identifier) currently in effect for the job. If the CCSID of the job is 65535, this buffer is assumed to be represented in the default CCSID of the job. bufSize (Input) The length of the buffer information. If bufSize is specified as 0, the length of bufSize will be calculated. Authorities No authorization is required. Return Value gsk_attribute_set_buffer() returns an integer. Possible values are: [GSK_OK] gsk_attribute_set_buffer() was successful. [GSK_ATTRIBUTE_INVALID_ID] The bufID value is not a valid identifier. [GSK_ATTRIBUTE_INVALID_LENGTH] The bufSize specified or the length of buffer is not valid. [GSK_INVALID_HANDLE] my_gsk_handle is not a valid handle that was received from issuing gsk_environment_open() or gsk_secure_soc_open(). [GSK_AS400_ERROR_INVALID_POINTER] The buffer pointer is not valid. Secure Sockets APIs 17
