char *t_strerror(int errnum);
General
description
Maps the error number in
errnum that corresponds to an
XTI error to a language-dependent error message string and returns
a pointer to the string. The string pointed to should not be modified
by the program, but may be overwritten by a subsequent call to the
t_strerror function. The string is not terminated by a newline character.
If the calling program is operating in any one of the C, POSIX, SAA
or S370 locales, then the
error message string describing the value in
t_errno is identical
to the comments following the
t_errno codes defined in <xti.h>.
Note that no message number is prefixed to the message text in this
situation. If an error code is unknown, and the language is English,
t_strerror() returns the string:
"<error>: error unknown"
where <error>
is the error number supplied as input. In other languages, an equivalent
text is provided.
Valid states: All - except for T_UNINIT
Returned value
t_strerror() returns a pointer to the generated message string.
