How can I get the linker to search all libraries? I am trying to use the directory functions, opendir, readdir, closedir, etc. The header dirent.h contains the declarations but I have had little success in linking the code. There seems to be no decent way to locate the library that contains any specific entry point and I don't seem to be able to get the linker to search all libraries. The documentation for optlink is, at best, vague. I set the LIB env. variable to the directory that contains the DM libraries but that did not seem to be enough. Using a strings command, I found the entry points in psxdll.lib. The code linked but then failed when the dll was not found. There is no psx*.dll in the system. |

The easy way to find the entry points is to just grep for them across the lib files. You can also use the lib command to generate .lst files from the libraries, and then you can see what each library defines.
As for opendir, etc., those are part of the posix subsystem. I recommend instead using FindFirstFile/FindNextFile.
