+FUNCTION
+<<psignal>>---print a signal message on standard error
+
+INDEX
+	psignal
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	void psignal(int <[signal]>, const char *<[prefix]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	void psignal(<[signal]>, <[prefix]>)
+	int <[signal]>;
+	const char *<[prefix]>;
+
+DESCRIPTION
+Use <<psignal>> to print (on standard error) a signal message
+corresponding to the value of the signal number <[signal]>.
+Unless you use <<NULL>> as the value of the argument <[prefix]>, the
+signal message will begin with the string at <[prefix]>, followed by a
+colon and a space (<<: >>). The remainder of the signal message is one
+of the strings described for <<strsignal>>.
+
+RETURNS
+<<psignal>> returns no result.
+
+PORTABILITY
+POSIX.1-2008 requires <<psignal>>, but the strings issued vary from one
+implementation to another.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
