## Detailed Description

## Function Documentation

KRB5_LIB_FUNCTION void KRB5_LIB_CALL krb5_clear_error_message | ( | krb5_context | context | ) |

Clears the error message from the Kerberos 5 context.

Parameters:

  | context | The Kerberos 5 context to clear

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_eai_to_heim_errno | ( | int | eai_errno,
|  | int | system_error |
| ) |  |  |

Convert the getaddrinfo() error code to a Kerberos et error code.

Parameters:

  | eai_errno | contains the error code from getaddrinfo().
  | system_error | should have the value of errno after the failed getaddrinfo().

Returns:
  Kerberos error code representing the EAI errors.

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_h_errno_to_heim_errno | ( | int | eai_errno | ) |

Convert the gethostname() error code (h_error) to a Kerberos et error code.

Parameters:

  | eai_errno | contains the error code from gethostname().

Returns:
  Kerberos error code representing the gethostname errors.

KRB5_LIB_FUNCTION void KRB5_LIB_CALL krb5_set_error_message | ( | krb5_context | context,
|  | krb5_error_code | ret,
|  | const char * | fmt,
|  |  | ... |
| ) |  |  |

Set the context full error string for a specific error code. The error that is stored should be internationalized.

The if context is NULL, no error string is stored.

Parameters:

  | context | Kerberos 5 context
  | ret | The error code
  | fmt | Error string for the error code
  | ... | printf(3) style parameters.

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_vwarn | ( | krb5_context | context,
|  | krb5_error_code | code,
|  | const char * | fmt,
|  | va_list | ap |
| ) |  |  |

Log a warning to the log, default stderr, include the error from the last failure.

Parameters:

  | context | A Kerberos 5 context.
  | code | error code of the last error
  | fmt | message to print
  | ap | arguments
