These fields are set 60to 0 if the symbol is not found. 61.Pp 62The program 63.Xr kvm_mkdb 8 64builds a database from the running kernel's namelist. 65If the database matches the opened kernel, 66.Fn kvm_nlist 67uses it to speed lookups. 68.Sh RETURN VALUES 69The 70.Fn kvm_nlist 71function returns the number of invalid entries found. 72If the kernel symbol table was unreadable, -1 is returned. 73.Sh FILES 74.Bl -tag -width /var/db/kvm_netbsd.db -compact 75.It Pa /var/db/kvm_netbsd.db 76.El 77.Sh SEE ALSO 78.Xr kvm 3 , 79.Xr kvm_close 3 , 80.Xr kvm_getargv 3 , 81.Xr kvm_getenvv 3 , 82.Xr kvm_geterr 3 , 83.Xr kvm_getprocs 3 , 84.Xr kvm_open 3 , 85.Xr kvm_openfiles 3 , 86.Xr kvm_read 3 , 87.Xr kvm_write 3 , 88.Xr kvm_mkdb 8 89
