-.Nm sys_signame
-.Nd system signal messages
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In signal.h
-.Ft void
-.Fn psignal "unsigned sig" "const char *s"
-.Vt extern const char * const sys_siglist[] ;
-.Vt extern const char * const sys_signame[] ;
-.In string.h
-.Ft "char *"
-.Fn strsignal "int sig"
-.Sh DESCRIPTION
-The
-.Fn psignal
-and
-.Fn strsignal
-functions locate the descriptive message
-string for a signal number.
-.Pp
-The
-.Fn strsignal
-function accepts a signal number argument
-.Fa sig
-and returns a pointer to the corresponding message string.
-.Pp
-The
-.Fn psignal
-function accepts an signal number argument
-.Fa sig
-and writes it to the standard error.
-If the argument
-.Fa s
-is
-.Pf non- Dv NULL
-and does not point to the null character,
-.Fa s
-is written to the standard error file descriptor
-prior to the message string,
-immediately followed by a colon and a space.
-If the signal number is not recognized
-.Pq Xr sigaction 2 ,
-the string
-.Dq "Unknown signal
-is produced.
-.Pp
-The message strings can be accessed directly
-through the external array
-.Va sys_siglist ,
-indexed by recognized signal numbers.
-The external array
-.Va sys_signame
-is used similarly and
-contains short, lower-case abbreviations for signals
-which are useful for recognizing signal names
-in user input.
-The defined variable
-.Dv NSIG
-contains a count of the strings in
-.Va sys_siglist
-and
-.Va sys_signame .
-.Sh SEE ALSO
-.Xr sigaction 2 ,
-.Xr perror 3 ,
-.Xr strerror 3
-.Sh HISTORY
-The
-.Fn psignal
-function appeared in
-.Bx 4.2 .
