NAME

     krb5_principal_get_realm, krb5_principal_get_comp_string - decompose a
     principal

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     const char *
     krb5_principal_get_realm(krb5_context context, krb5_principal principal)

     const char *
     krb5_principal_get_comp_string(krb5_context context,
             krb5_principal principal, unsigned int component)

DESCRIPTION

     These functions return parts of the principal, either the realm or a spe-
     cific component. The returned string points to data inside the principal,
     so they are valid only as long as the principal exists.

     The component argument to krb5_principal_get_comp_string() is the compo-
     nent number to return, from zero to the total number of components minus
     one. If a the requested component number is out of range, NULL is re-
     turned.

     These functions can be seen as a replacement for the krb5_princ_realm(),
     krb5_princ_component() and related macros, described as intermal in the
     MIT API specification. A difference is that these functions return
     strings, not krb5_data. A reason to return krb5_data was that it was be-
     lieved that principal components could contain binary data, but this be-
     lief was unfounded, and it has been decided that principal components are
     infact UTF8, so it's safe to use zero terminated strings.

     It's generally not necessary to look at the components of a principal.
