* gdialogs.c: Support ui->ctx to be NULL, as file.c will set this to NULL for background operations. 1999-03-10 Miguel de Icaza <miguel@nuclecu.unam.mx> * utilunix.c (g_readlink): New function. Wraps all the nonsense of readlink into a nice routine. * filegui.c: Support ui->ctx to be NULL, as file.c will set this to NULL for background operations. * background.c (do_background): Handle EINTR in dup2.
