+FUNCTION
+	<<strerror_r>>---convert error number to string and copy to buffer
+
+INDEX
+	strerror_r
+
+ANSI_SYNOPSIS
+	#include <string.h>
+	char *strerror_r(int <[errnum]>, char *<[buffer]>, size_t <[n]>);
+
+TRAD_SYNOPSIS
+	#include <string.h>
+	char *strerror_r(<[errnum]>, <[buffer]>, <[n]>)
+	int <[errnum]>;
+	char *<[buffer]>;
+	size_t <[n]>;
+
+DESCRIPTION
+<<strerror_r>> converts the error number <[errnum]> into a
+string and copies the result into the supplied <[buffer]> for
+a length up to <[n]>, including the NUL terminator. The value of 
+<[errnum]> is usually a copy of <<errno>>.  If <<errnum>> is not a known 
+error number, the result is the empty string.
+
+See <<strerror>> for how strings are mapped to <<errnum>>.
+
+RETURNS
+This function returns a pointer to a string.  Your application must
+not modify that string.
+
+PORTABILITY
+<<strerror_r>> is a gnu extension.
+
+<<strerror_r>> requires no supporting OS subroutines.
