[yuchan]

Hello everyone.


I am writing some program which change password of smb users.

so  i use remote_change_password function and try it  but seg-fault whenever
call unicode_to_unix_char() function.

blow my code


int setsambapassword( const char *remotehost, char *username, const char
*smboldpassword, char *password)
{
        char err[1024];
        int ret;

        memset( &err, '\0', sizeof(err));

        ret = remote_password_change(remotehost, username, smboldpassword,
password, err, sizeof(err));

        if( *err)
                fprintf(stderr, err);
        return ret;
}

and compiling with follow option

gcc -o testsamba testsamba.c -lsmbclinet /usr/lib/libsmbclinet.a -g

and run using gdb

gdb ./testsamba
gdb> run

Program received signal SIGSEGV, Segmentation fault,
0x080850dc in unicode_to_unix_char()

gdb) where
#0 0x08085dc in unicode_to_unix_char()
