krb5_read_password - Read a password from keyboard input.
===========================================================
..
.. c:function:: krb5_error_code krb5_read_password(krb5_context context, const char * prompt, const char * prompt2, char * return_pwd, unsigned int * size_return)
..
:param:
**[in]** **context** - Library context
**[in]** **prompt** - First user prompt when reading password
**[in]** **prompt2** - Second user prompt (NULL to prompt only once)
**[out]** **return_pwd** - Returned password
**[inout]** **size_return** - On input, maximum size of password; on output, size of password read
..
:retval:
- 0 Success
:return:
- Error in reading or verifying the password Kerberos error codes
..
This function reads a password from keyboard input and stores it in *return_pwd* . *size_return* should be set by the caller to the amount of storage space available in *return_pwd* ; on successful return, it will be set to the length of the password read.
*prompt* is printed to the terminal, followed by":", and then a password is read from the keyboard.
If *prompt2* is NULL, the password is read only once. Otherwise, *prompt2* is printed to the terminal and a second password is read. If the two passwords entered are not identical, KRB5_LIBOS_BADPWDMATCH is returned.
Echoing is turned off when the password is read.
