+.SH NAME
+psiginfo, psignal
+\(em write signal information to standard error
+.SH SYNOPSIS
+.LP
+.nf
+#include <signal.h>
+.P
+void psiginfo(const siginfo_t *\fIpinfo\fP, const char *\fImessage\fP);
+void psignal(int \fIsignum\fP, const char *\fImessage\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIpsiginfo\fR()
+and
+\fIpsignal\fR()
+functions shall write a language-dependent message associated with a
+signal number to the standard error stream as follows:
+.IP " *" 4
+First, if
+.IR message
+is not a null pointer and is not the empty string, the string pointed
+to by the
+.IR message
+argument shall be written, followed by a
+<colon>
+and a
+<space>.
+.IP " *" 4
+Then the signal description string associated with
+.IR signum
+or with the signal indicated by
+.IR pinfo
+shall be written, followed by a
+<newline>.
+.P
+For
+\fIpsiginfo\fR(),
+the application shall ensure that the argument
+.IR pinfo
+references a valid
+.BR siginfo_t
+structure. For
+\fIpsignal\fR(),
+if
+.IR signum
+is not a valid signal number, the behavior is implementation-defined.
+.P
+The
+\fIpsiginfo\fR()
+and
+\fIpsignal\fR()
+functions shall not change the orientation of the standard error stream.
+.P
+The
+\fIpsiginfo\fR()
+and
+\fIpsignal\fR()
+functions shall mark for update the last data modification and last file
+status change timestamps of the file associated with the standard error
+stream at some time between their successful completion and
+\fIexit\fR(),
+\fIabort\fR(),
+or the completion of
+\fIfflush\fR()
+or
+\fIfclose\fR()
+on
+.IR stderr .
+.P
+The
+\fIpsiginfo\fR()
+and
+\fIpsignal\fR()
+functions shall not change the setting of
+.IR errno
+if successful.
+.P
+On error, the
+\fIpsiginfo\fR()
+and
+\fIpsignal\fR()
+functions shall set the error indicator for the stream to which
+.IR stderr
+points, and shall set
+.IR errno
+to indicate the error.
+.P
+Since no value is returned, an application wishing to check for error
+situations should set
+.IR errno
+to 0, then call
+\fIpsiginfo\fR()
+or
+\fIpsignal\fR(),
+then check
+.IR errno .
+.SH "RETURN VALUE"
+These functions shall not return a value.
+.SH ERRORS
+Refer to
+.IR "\fIfputc\fR\^(\|)".
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+As an alternative to setting
+.IR errno
+to zero before the call and checking if it is non-zero afterwards,
+applications can use
+\fIferror\fR()
+to detect whether
+\fIpsiginfo\fR()
+or
+\fIpsignal\fR()
+encountered an error.
+.P
+An application wishing to use this method to check for error situations
+should call
+.IR clearerr ( stderr )
+before calling
+\fIpsiginfo\fR()
+or
+\fIpsignal\fR(),
+then if
+.IR ferror ( stderr )
+returns non-zero, the value of
+.IR errno
+indicates which error occurred.
+.SH RATIONALE
+System V historically has
+\fIpsignal\fR()
+and
+\fIpsiginfo\fR()
+in
+.IR <siginfo.h> .
+However, the
+.IR <siginfo.h> 
+header is not specified in the Base Definitions volume of POSIX.1\(hy2017, and the type
+.BR siginfo_t
+is defined in
+.IR <signal.h> .
+.SH "FUTURE DIRECTIONS"
+None.
+.SH "SEE ALSO"
+.IR "\fIfputc\fR\^(\|)",
+.IR "\fIperror\fR\^(\|)",
+.IR "\fIstrsignal\fR\^(\|)"
