This function activates the new context.

Returns:

New sfContext object

void sfContext_destroy(const sfContext *context)

• context – Context to destroy

bool sfContext_isExtensionAvailable(const char *name)

Check whether a given OpenGL extension is available.

Parameters:

• name – Name of the extension to check for

Address of the OpenGL function, 0 on failure

sfContextSettings sfContext_getSettings(const sfContext *context)

Get the settings of the context.

Note that these settings may be different than the ones passed to the constructor; they are indeed adjusted if the original settings are not directly supported by the system.

Parameters:

• context – Context object

Returns:

Structure containing the settings

uint64_t sfContext_getActiveContextId(void)
