t_error(3) Library Functions Manual 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 stan- dards as follows: t_error: XPG4-UNIX Refer to the standards(5) reference page for more information about in- dustry standards and associated tags. PARAMETERS The following table summarizes the relevance of input parameter data before and after t_error() is called: center, tab (@); lb lb lb l c c. 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 func- tion. 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 mes- sage for the current value contained in errno. The error number, t_er- rno, is set only when an error occurs and is not cleared when XTI func- tions 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 de- scribing 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(3C) 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 maxi- mum 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.
