9 SYNOPSIS
10 #include <stdio.h>
11 void psignal(int <[signal]>, const char *<[prefix]>);
12
13 DESCRIPTION
14 Use <<psignal>> to print (on standard error) a signal message
15 corresponding to the value of the signal number <[signal]>.
16 Unless you use <<NULL>> as the value of the argument <[prefix]>, the
17 signal message will begin with the string at <[prefix]>, followed by a
18 colon and a space (<<: >>). The remainder of the signal message is one
19 of the strings described for <<strsignal>>.
20
21 RETURNS
22 <<psignal>> returns no result.
23
24 PORTABILITY
25 POSIX.1-2008 requires <<psignal>>, but the strings issued vary from one
26 implementation to another.
27
28 Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
29 <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
