.Dd December 28, 2000 .Dt UTRACE 2 .Os .Sh NAME .Nm utrace .Nd insert user record to ktrace records .Sh LIBRARY .Lb libc .Sh SYNOPSIS .Fd #include <sys/types.h> .Fd #include <sys/param.h> .Fd #include <sys/time.h> .Fd #include <sys/uio.h> .Fd #include <sys/ktrace.h> .Ft int .Fn utrace "const char *label" "void *addr" "size_t len" .Sh DESCRIPTION Adds a record to process trace with information supplied by user. The record is identified by .Fa label and contains .Fa len bytes from memory pointed to by .Fa addr . This call has only effect if the caller process is being traced. .Sh RETURN VALUES Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and .Va errno is set to indicate the error. .Sh ERRORS l -tag -width Er t Bq Er ENOSYS Currently running kernel was compiled without .Xr ktrace 2 support (option KTRACE). t Bq Er EINVAL Specified data length .Fa len was bigger than .Dv KTR_USER_MAXLEN . .El .Sh SEE ALSO .Xr kdump 1 , .Xr ktrace 1 , .Xr ktruss 1 , .Xr fktrace 2 , .Xr ktrace 2 , .Xr options 4 .Sh HISTORY The .Fn utrace system call first appeared in .Fx 2.2 . It was added to .Nx in .Nx 1.6 . The .Fa label argument is .Nx extension.
