27 | Initializes a new read-only memory stream which will use the specified buffer | |
2bf8e4eb | 28 | {\it data} of length {\it len}. The stream does not take ownership of the |
08890e27 | 29 | buffer, i.e. the buffer will not be deleted in its destructor. |

08890e27 | 33 | Creates a new read-only memory stream, initializing it with the |
96461cc2 VZ |
34 | data from the given output stream \arg{stream}. |

37 | ||
38 | Creates a new read-only memory stream, initializing it with the | |
39 | data from the given input stream \arg{stream}. | |
40 | ||
41 | The \arg{len} argument specifies the amount of data to read from | |
42 | the \arg{stream}. Setting it to {\it wxInvalidOffset} means that | |
43 | the \arg{stream} is to be read entirely (i.e. till the EOF is reached). | |

84 | ||
605d715d | 85 | If {\it data} is NULL, then it will initialize a new empty buffer which will |
2bf8e4eb | 86 | grow if required. |

90 | If the buffer is created, it will be destroyed at the destruction of the | |

101 | \constfunc{size\_t}{CopyTo}{\param{char *}{buffer}, \param{size\_t }{len}} | |
102 | ||
103 | CopyTo allowed you to transfer data from the internal buffer of | |
605d715d | 104 | wxMemoryOutputStream to an external buffer. {\it len} specifies the size of |
f439844b GL |
105 | the buffer. |
106 | ||
107 | \wxheading{Returned value} | |
108 | ||
109 | CopyTo returns the number of bytes copied to the buffer. Generally it is either | |
110 | len or the size of the stream buffer. | |
