krb5_error_code `krb5_build_principal`(krb5_context context, krb5_principal * princ, unsigned int rlen, const char * realm, ...)

param: | [in] context - Library context [out] princ - Principal name [in] rlen - Realm name length [in] realm - Realm name

Call `krb5_free_principal()` to free princ when it is no longer needed.

Note

`krb5_build_principal()` and `krb5_build_principal_alloc_va()` perform the same task. `krb5_build_principal()` takes variadic arguments. `krb5_build_principal_alloc_va()` takes a pre-computed varargs pointer.
