- NAME
- getcwd -- get absolute pathname for current working directory
-
- SYNOPSIS
- char *getcwd (char pathname[len], len)
-
- DESCRIPTION
- Copy the absolute pathname for the current working directory into
- the supplied buffer and return a pointer to the buffer. If the
- current directory's path doesn't fit in LEN characters, the result
- is NULL and errno is set.
-
- BUGS
- Emulated via the getwd() call, which is reasonable for most
- systems that do not have getcwd().
