#include <unistd.h> int symlink(const char *exists, const char *new);
MSDOS doesn't support symbolic links. However, DJGPP supports
"symlinks" to DJGPP programs. This function simulates a symlink
between two `.exe' files in the DJGPP style. It creates a program
whose name is pointed to by new which, when run, will actually
execute the program exists passing it the string pointed by
new in argv[0] (some programs change their behavior
depending on what's passed in argv[0]). The file referred to by
exists doesn't really have to exist when this function is called.
If exists points to an existing file, the function checks
that it is a DJGPP executable; if not, the call will fail with
EXDEV.
Both new and exists can point to a name with or without the `.exe' extension.
Note that both exists and new must specify file names which
reside in the same
directory (this is a restriction of the DJGPP "symlinks"); the
function will fail and set errno to EXDEV if they aren't.
This functions runs the `stubify' and `stubedit' programs, so they should be somewhere on your `PATH' for the function to succeed. (These programs come with the DJGPP development distribution.)
Zero in case of success, -1 in case of failure (and errno set to
the appropriate error code).
