Info

[EPIPE] [EUNATCH] The specified descriptor does not reference a socket. Broken pipe. The protocol required to support the specified address family is not available at this time. Any errno that can be returned by send() can be returned by this API. See Sockets APIs for a description of the errno values it can return. Usage Notes 1. There is no maximum length of the data that can be written. 2. It is strongly suggested that you do not mix the gsk_secure_soc_write() API with any of the sockets write functions. SSL and socket reads and writes can be mixed, but they must be performed in matched sets. If a client application writes 100 bytes of data using one or more of the socket send() calls, then the server application must read exactly 100 bytes of data using one or more of the socket recv() calls. This is also true for gsk_secure_soc_write() API. 3. The amtWritten value is set to zero when return value is not GSK_OK. Error Messages Message ID Error Message Text CPE3418 E Possible APAR condition or hardware failure. CPF9872 E Program or service program &1 in library &2 ended. Reason code &3. CPFA081 E Unable to set return value or error code.

The gsk_strerror() function is used to retrieve an error message and associated text string that describes a return value that was returned from calling a GSKit API. Parameters gsk_return_value (Input) The return value received from a GSKit API. Authorities No authorization is required. Return Value gsk_strerror() returns a pointer to the return value text. Usage Notes 1. gsk_strerror() returns a pointer to the string. The null-terminated string is stored in the CCSID of the job. 2. If a gsk_return_value is specified for which there is no corresponding description, an Unknown Error string is returned.
