SYNOPSIS
#include <xti.h>

extern int t_nerr;
LIBRARY
XTI Library (libxti.a)
STANDARDS
Interfaces documented on this reference page conform to industry stan‐
dards as follows:
t_error(): XNS4.0, XNS5.0

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: This is a meaningful parameter. This is not a meaning‐
ful parameter. Points to a user-supplied error message character
string that lends proper context to the nature of the detected error.
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_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() 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.
ERRORS
No errors are defined for the t_errno() function.
VALID STATES
The t_errno() function can be called in any transport provider state
except T_UNINIT.
RETURN VALUE
Upon successful completion, a value of 0 (zero) is returned.
