Default handler for _IO_LSEEK messages
#include <sys/iofunc.h> int iofunc_lseek_default( resmgr_context_t* ctp, io_lseek_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_lseek_default() function implements POSIX semantics for the client's lseek() call, which is received as an _IO_LSEEK message by the resource manager.
You can place this function directly into the io_funcs table passed to resmgr_attach(), at the lseek position, or you can call iofunc_func_init() to initialize all of the functions to their default values.
The iofunc_lseek_default() function calls iofunc_lseek() to do the actual work.
