In the latter case, \fIerrno\fP is set to indicate the error. +.SH ERRORS +.TP +.B EACCES +Search permission denied for directory in file's path prefix. +.TP +.B EEXIST +Unable to generate a unique filename. +.TP +.B EINTR +The call was interrupted by a signal. +.TP +.B EMFILE +Too many file descriptors in use by the process. +.TP +.B ENFILE +Too many files open in the system. +.TP +.B ENOSPC +There was no room in the directory to add the new filename. +.TP +.B EROFS +Read-only filesystem. +.SH "CONFORMING TO" +SVID 3, POSIX, BSD 4.3, ISO 9899, SUSv2 +.SH NOTES +An error message may be written to \fIstdout\fP if the stream +cannot be opened. +.LP +The standard does not specify the directory that \fItmpfile()\fP +will use.
