t_error(3xti)															     t_error(3xti)

Name
       t_error - produces error message

Syntax
       #include <xti.h>

       int t_error(errmsg)
       char *errmsg;
       extern char *t_errlist[];
       extern int t_nerr;

Arguments
       errmsg	 Is a user-supplied error message that gives context to the error.

Description
       The  function  produces a message on the standard error output that describes the last error encountered during a call to a transport func-
       tion.

       The function prints the user-supplied error message followed by a colon and a standard error message  for  the  current	error  defined	in
       t_errno. If t_errno is [TSYSERR], also prints a standard message for the current value contained in errno.

       To simplify variant formatting of messages, the array of message strings t_errlist is provided: t_errno can be used as an index in this ta-
       ble to get the message string without the newline. The t_nerr is the largest message number provided for in the t_errlist table.

       The t_errno variable is set only when an error occurs and is not cleared on successful calls.

Examples
       If a function fails on transport endpoint fd2 because a bad address was given, the following call may follow the failure:
       t_error ("t_connect failed on fd"):

       The diagnostic message to be printed would look like:
       t_connect failed on fd2: Incorrect transport address format
       where "Incorrect transport address format" identifies the specific error that occurred, and "t_connect failed on fd2" tells the user  which
       function failed on which transport endpoint.

Return Values
       Upon successful completion, a value of 0 is returned. On failure, a value of -1 is returned, and t_errno is set to indicate the error.

Diagnostics
       On failure, t_errno is set to the following:

       [TNOTSUPPORT]	   This function is not supported by the current implementation of XTI.
