This value points to a static data area that is overwritten by each call to \fBptsname()\fR. Upon failure, \fBptsname()\fR returns \fINULL\fR. This could occur if \fIfildes\fR is an invalid file descriptor or if the slave device name does not exist in the file system. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
