Using This Function
This function is useful when a project and its related files are distributed to multiple users who
may place them in a different directory on each machine. If your program needs to access a file
that is in the same directory as the project, you can use GetProjectDir and
MakePathname to construct the full pathname.
Example
char *fileName;
char projectDir[MAX_PATHNAME_LEN];
char fullPath[MAX_PATHNAME_LEN];
fileName = "myfile";
if (GetProjectDir (projectDir) < 0)
FmtOut ("Project is untitled\n");
else
MakePathname (projectDir, fileName, fullPath);
