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 .Fn psiginfo function is similar to .Fn psignal , except that the signal number information is taken from the .Fa si argument which is a .Vt siginfo_t structure. .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, upper-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 . +.Pp +The +.Fn sig2str +function translates the signal number +.Fa signum +to the signal name, without the +.Dq SIG +prefix, and stores it at the location specified by +.Fa str , +which should be large enough to hold the name and the terminating +.Dv NUL +byte. +The symbol +.Dv SIG2STR_MAX +gives the maximum size in bytes required. +.Pp +The +.Fn str2sig +function translates the signal name +.Fa str +to a signal number and stores it in the location referenced by +.Fa pnum . +The name in +.Fa str +can be either the name of the signal, with or without the +.Dq SIG +prefix, or a decimal number. .Sh SEE ALSO .Xr sigaction 2 , .Xr perror 3 , .Xr strerror 3 +.Sh STANDARDS +The +.Fn psignal +and +.Fn psiginfo +functions are defined by +.St -p1003.1-2008 +, while the +.Fn sig2str +and +.Fn str2sig +functions are defined by +.St -p1003.1-2024 . .Sh HISTORY The .Fn psignal function appeared in .Bx 4.2 .
