NAME

     krb5_data krb5_data_zero krb5_data_free krb5_free_data_contents
     krb5_free_data krb5_data_alloc krb5_data_realloc krb5_data_copy
     krb5_copy_data -- operates on the Kerberos datatype krb5_data.

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     #include <krb5.h>

     struct krb5_data;

     void
     krb5_data_zero(krb5_data *p);

     void
     krb5_data_free(krb5_data *p);

     void
     krb5_free_data_contents(krb5_context context, krb5_data *p);

     void
     krb5_free_data(krb5_context context, krb5_data *p);

     krb5_error_code
     krb5_data_alloc(krb5_data *p, int len);

     krb5_error_code
     krb5_data_realloc(krb5_data *p, int len);

     krb5_error_code
     krb5_data_copy(krb5_data *p, const void *data, size_t len);

     krb5_error_code
     krb5_copy_data(krb5_context context, const krb5_data *indata,
	 krb5_data **outdata);

DESCRIPTION

     The krb5_data structure holds a data element.  The structure contains two
     public accessible elements length (the length of data) and data (the data
     itself).  The structure must always be initiated and freed by the func-
     tions documented in this manual.

     krb5_data_zero() resets the content of p.

     krb5_data_free() free the data in p.

     krb5_free_data_contents() works the same way as krb5_data_free.  The
     diffrence is that krb5_free_data_contents is more portable (exists in MIT
     api).

     krb5_free_data() frees the data in p and p itself .

     krb5_data_alloc() allocates len bytes in p Returns 0 or an error.

     krb5_data_realloc() reallocates the length of p to the length in len.
     contain anything needs to be freed.  outdata should be freed using
     krb5_free_data().	Returns 0 or an error.
