t_error(3)
NAME
  t_error - Produces error message

LIBRARY
  XTI Library (libxti.a)

SYNOPSIS
  #include <xti.h>

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

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  t_error():  XNS4.0

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

PARAMETERS
  The following table summarizes the relevance of input parameter data before
  and after t_error() is called:

		     Parameter	 Before Call   After Call
		     ____________________________________
		     errmsg	      y		   n
  Notes to table:
  y    This is a meaningful parameter.
  n    This is not a meaningful parameter.

  errmsg    Points to a user-supplied error message character string that
	    lends proper context to the nature of the detected error.

VALID STATES
  The t_errno() function can be called in any transport provider state except
  T_UNINIT.

DESCRIPTION
  The t_error() function is a general utility function used to produce an
  error message on the standard error output device. The error message
  describes the last error encountered during execution of an XTI function.
  The user-supplied error message is printed, followed by a colon and a
  standard error message for the current error defined in t_errno.  When
  t_errno is [TSYSERR], t_error() also prints a standard error message for
  the current value contained in errno.	 The error number, t_errno, is set
  only when an error occurs and is not cleared when XTI functions execute
  successfully.

  The language for error message strings written by t_error() is defined by
  the implementation. If it is English, the error message string describing
  the value in t_errno is identical to the comments following the t_errno
  codes defined in xti.h. The contents of the error message strings
  describing the value in errno are the same as those returned by the
  strerror(3) function with an argument of errno.

  To simplify variant formatting of messages, the array of message strings
  named t_errlist is specified. Variable t_errno may be used as an index into
  this table to get a relevant message string without an ending newline
  character. External variable t_nerr specifies the maximum number of
  messages in the t_errlist table.

RETURN VALUE
  Upon successful completion, a value of 0 (zero) is returned.

ERRORS
  No errors are defined for the t_errno() function.
