Function Documentation

◆ OSDynLoad_Acquire()

OSDynLoad_Error OSDynLoad_Acquire ( char const *  name,
OSDynLoad_Module *  outModule 
)

Load a module.

If the module is already loaded, increase reference count. Similar to LoadLibrary on Windows.

◆ OSDynLoad_FindExport()

OSDynLoad_Error OSDynLoad_FindExport ( OSDynLoad_Module  module,
OSDynLoad_ExportType  exportType,
char const *  name,
void **  outAddr 
)

Retrieve the address of a function or data export from a module.

Similar to GetProcAddress on Windows.

◆ OSDynLoad_Release()

void OSDynLoad_Release ( OSDynLoad_Module  module)

Free a module handle returned from OSDynLoad_Acquire.

Will decrease reference count and only unload the module if count reaches 0. Similar to FreeLibrary on Windows.

◆ OSDynLoad_SetAllocator()

OSDynLoad_Error OSDynLoad_SetAllocator ( OSDynLoadAllocFn  allocFn,
OSDynLoadFreeFn  freeFn 
)

Set the allocator functions to use for dynamic loading.

◆ OSDynLoad_GetAllocator()

OSDynLoad_Error OSDynLoad_GetAllocator ( OSDynLoadAllocFn *  outAllocFn,
OSDynLoadFreeFn *  outFreeFn 
)

Get the allocator functions used for dynamic loading.

◆ OSDynLoad_SetTLSAllocator()

OSDynLoad_Error OSDynLoad_SetTLSAllocator ( OSDynLoadAllocFn  allocFn,
OSDynLoadFreeFn  freeFn 
)

Set the allocator functions to use for thread local storage.

◆ OSDynLoad_GetTLSAllocator()

OSDynLoad_Error OSDynLoad_GetTLSAllocator ( OSDynLoadAllocFn *  outAllocFn,
OSDynLoadFreeFn *  outFreeFn 
)

Get the allocator functions used for thread local storage.

◆ OSDynLoad_GetLoaderHeapStatistics()

OSDynLoad_Error OSDynLoad_GetLoaderHeapStatistics ( OSDynLoad_LoaderHeapStatistics *  outLoaderHeapStatistics)

Get loader heap statistics.

◆ OSDynLoad_GetModuleName()

OSDynLoad_Error OSDynLoad_GetModuleName ( OSDynLoad_Module  module,
char *  nameBuf,
int32_t *  nameBufSize 
)

Gets the name for a given module handle.

Using the value "-1" as module handle gets the name of the running main rpl

◆ OSDynLoad_GetNumberOfRPLs()

int32_t OSDynLoad_GetNumberOfRPLs ( )

Gets the number of currently loaded RPLs.

Always returns 0 on release versions of CafeOS. Requires OSGetSecurityLevel() > 0.

◆ OSDynLoad_GetRPLInfo()

BOOL OSDynLoad_GetRPLInfo ( uint32_t  first,
uint32_t  count,
OSDynLoad_NotifyData *  outInfos 
)

Get information about the currently loaded RPLs.

Parameters
firstthe index of the first RPL to retrieve info for.
countthe number of RPLs to retrieve info for
outInfosbuffer of RPL info to be filled, should be an array of at least count size.

Always returns FALSE on release versions of CafeOS. Requires OSGetSecurityLevel() > 0.

◆ OSDynLoad_IsModuleLoaded()

OSDynLoad_Error OSDynLoad_IsModuleLoaded ( char const *  name,
OSDynLoad_Module *  outModule 
)

Checks if a module is already loaded.

Does not load any modules.

Returns OS_DYNLOAD_OK on success.

◆ OSDynLoad_AddNotifyCallback()

OSDynLoad_Error OSDynLoad_AddNotifyCallback ( OSDynLoadNotifyFunc  notifyFn,
void *  userContext 
)

Registers a callback that's called whenever a new .rpl is loaded or unloaded.

◆ OSDynLoad_DelNotifyCallback()

OSDynLoad_Error OSDynLoad_DelNotifyCallback ( OSDynLoadNotifyFunc  notifyFn,
void *  userContext 
)

Removes a previously added a callback.

◆ rpl_entry()

int rpl_entry ( OSDynLoad_Module  module,
OSDynLoad_EntryReason  reason 
)

The prototype for an RPL entry point.

Use this instead of main when creating .rpl files
