- Loads a user-defined Windows resource as a string. If the resource is
- found, the function creates a new character array and copies the data into
- it. A pointer to this data is returned. If unsuccessful, @NULL is returned.
+ Loads an object from Windows resource file.
- The resource must be defined in the @c .rc file using the following syntax:
+ This function loads the resource with the given name and type from the
+ resources embedded into a Windows application.
+ The typical use for it is to load some data from the data files embedded
+ into the program itself. For example, you could have the following fragment
+ in your @c .rc file
@code
- myResource TEXT file.ext
+ mydata MYDATA "myfile.dat"
+ @endcode
+ and then use it in the following way:
+ @code
+ const void* data = NULL;
+ size_t size = 0;
+ if ( !wxLoadUserResource(&data, &size, "mydata", "MYDATA") ) {
+ ... handle error ...
+ }
+ else {
+ // Use the data in any way, for example:
+ wxMemoryInputStream is(data, size);
+ ... read the data from stream ...
+ }
@endcode
- Where @c file.ext is a file that the resource compiler can find.
+ @param outData Filled with the pointer to the data on successful return.
+ Notice that this pointer does @em not need to be freed by the caller.
+ @param outLen Filled with the length of the data in bytes.
+ @param resourceName The name of the resource to load.
+ @param resourceType The type of the resource in usual Windows format, i.e.
+ either a real string like "MYDATA" or an integer created by the
+ standard Windows @c MAKEINTRESOURCE() macro, including any constants
+ for the standard resources types like @c RT_RCDATA.
+ @param module The @c HINSTANCE of the module to load the resources from.
+ The current module is used by default.
+ @return true if the data was loaded from resource or false if it couldn't
+ be found (in which case no error is logged) or was found but couldn't
+ be loaded (which is unexpected and does result in an error message).

+ @c wxSIGTERM under Windows. Moreover, under Windows, @c wxSIGTERM is

it will be filled with a value from the @c wxKillError enum:
