.Sh SYNOPSIS
|
|
.Fd #include <krb5.h>
|
|
.Ft "const char *"
|
|
.Fn krb5_principal_get_realm "krb5_context context" "krb5_principal principal"
|
|
.Ft "const char *"
|
|
.Fn krb5_principal_get_comp_string "krb5_context context" "krb5_principal principal" "unsigned int component"
|
|
.Sh DESCRIPTION
|
|
These functions return parts of the
|
|
.Fa principal ,
|
|
either the realm or a specific component. The returned string points
|
|
to data inside the principal, so they are valid only as long as the
|
|
principal exists.
|
|
.Pp
|
|
The
|
|
.Fa component
|
|
argument to
|
|
.Fn krb5_principal_get_comp_string
|
|
is the component number to return, from zero to the total number of
|
|
components minus one. If a the requested component number is out of range,
|
|
.Dv NULL
|
|
is returned.
|
|
.Pp
|
|
These functions can be seen as a replacement for the
|
|
.Fn krb5_princ_realm ,
|
|
.Fn krb5_princ_component
|
|
and related macros, described as intermal in the MIT API
|
|
specification. A difference is that these functions return strings,
|
|
not
|
|
.Dv krb5_data .
|
|
A reason to return
|
|
.Dv krb5_data
|
|
was that it was believed that principal components could contain
|
|
binary data, but this belief was unfounded, and it has been decided
|
|
that principal components are infact UTF8, so it's safe to use zero
|
|
terminated strings.
|
|
.Pp
|
|
It's generally not necessary to look at the components of a principal.
