.Dd October 17, 2016 .Dt sysdecode_sigcode 3 .Os .Sh NAME .Nm sysdecode_sigcode .Nd lookup name of signal code .Sh LIBRARY .Lb libsysdecode .Sh SYNOPSIS n sys/types.h n stdbool.h n sysdecode.h .Ft const char * .Fn sysdecode_sigcode "int signal" "int si_code" .Sh DESCRIPTION The .Fn sysdecode_sigcode function returns a text description of the .Fa si_code field of the .Vt siginfo_t object associated with an instance of signal .Fa sig . The text description contains the name of the C macro whose value matches .Fa si_code . General purpose signal codes such as .Dv SI_USER are handled as well as signal-specific codes for .Dv SIGBUS , .Dv SIGCHLD , .Dv SIGFPE , .Dv SIGILL , .Dv SIGSEGV and .Dv SIGTRAP . If .Fa si_code does not represent a known signal code, .Fn sysdecode_sigcode returns .Dv NULL . .Sh RETURN VALUES The .Fn sysdecode_sigcode function returns a pointer to a signal code description or .Dv NULL if .Fa si_code is not a known signal code. .Sh SEE ALSO .Xr sysdecode_sigbus_code 3 , .Xr sysdecode_sigchld_code 3 , .Xr sysdecode_sigfpe_code 3 , .Xr sysdecode_sigill_code 3 , .Xr sysdecode_sigsegv_code 3 , .Xr sysdecode_sigtrap_code 3
