QByteArray::operator const char *() const

Returns a pointer to the data stored in the byte array. The pointer can be used to access the bytes that compose the array. The data is '\0'-terminated. The pointer remains valid as long as the array isn't reallocated or destroyed.

This operator is mostly useful to pass a byte array to a function that accepts a const char *.

You can disable this operator by defining QT_NO_CAST_FROM_BYTEARRAY when you compile your applications.

Note: A QByteArray can store any byte values including '\0's, but most functions that take char * arguments assume that the data ends at the first '\0' they encounter.
