Default handler for _IO_MMAP messages
#include <sys/iofunc.h> int iofunc_mmap_default ( resmgr_context_t * hdr, io_mmap_t * msg, iofunc_ocb_t * ocb );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iofunc_mmap_default() function provides functionality for the _IO_MMAP message. This message is private to the Memory Manager (a part of the Neutrino microkernel's procnto).
You can place this function directly into the io_funcs table passed to resmgr_attach(), at the mmap position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
Note that if the Process Manager is to be able to execute from this resource, then you must use the iofunc_mmap() function.
The iofunc_mmap_default() function calls iofunc_mmap() to do the actual work.
