+.SH VERSIONS
+The glibc version of
+.BR getdtablesize ()
+calls
+.BR getrlimit (2)
+and returns the current
+.B RLIMIT_NOFILE
+limit, or
+.B OPEN_MAX
+when that fails.
+.\" The libc4 and libc5 versions return
+.\" .B OPEN_MAX
+.\" (set to 256 since Linux 0.98.4).
+.PP
+Portable applications should employ
+.I sysconf(_SC_OPEN_MAX)
+instead of this call.
+.SH STANDARDS
+None.
+.SH HISTORY
+SVr4, 4.4BSD
+(first appeared in 4.2BSD).
