File and Path Function
int ttyname_r(int filedes, char *buf, size_t len);
Internationalization (I18n) Function Overview
The ttyname_r function is similar to the ttyname
function except that it is re-entrant by placing its result into the user-specified buffer
starting at buf with length len.
The function returns 0 if successful; otherwise an error number is returned.
The following errno errors are defined for this function:
EBADF - the filedes argument is not a valid file descriptor;
ENOTTY - the filedes is not associated with a terminal;
ERANGE - the buffer length len is too small to store the string to be returned.
There is no wide-character version of the function.
I18n Issues
On ANSI UTF-16 platforms, use a conversion function to convert the return
from ttyname_r to a wide-character string.
See Pathnames for a discussion of path and filename considerations in
an internationalized application.
Recommended Replacements*
*If you're already using the recommended function, see I18n Issues for other reasons why Globalyzer is detecting the function.
