# krb5_build_principal_alloc_va - Build a principal name, using a precomputed variable argument list.

krb5_error_code `krb5_build_principal_alloc_va`(krb5_context context, krb5_principal * princ, unsigned int rlen, const char * realm, va_list ap)

param: | [in] context - Library context [out] princ - Principal structure [in] rlen - Realm name length [in] realm - Realm name [in] ap - List of char * components, ending with NULL

retval: | 0 Success
return: | Kerberos error codes

Similar to `krb5_build_principal()` , this function builds a principal name, but its name components are specified as a va_list.

Use `krb5_free_principal()` to deallocate princ when it is no longer needed.
