annotate packages/io/fileio/current/src/fio.h @ 1283:6bb106b4ff93

* src/fio.h (CYG_FILEIO_SIGMASK_SET): Fixed a compiler warning about an unused variable. * src/devfs.cxx: prototype of dev_fo_select now matches implementation * include/fileio.h: changed definition of cyg_fileop_select to return a cyg_bool instead of int to match current implementations * src/misc.cxx: changed cyg_fileio_seltrue() to match prototype.
