libc
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.
_IO_LSEEK
message wasn't one of SEEK_SET
, SEEK_CUR
, or SEEK_END
, or the resulting position after the offset was applied resulted in a negative number (overflow).off_t
