**getcwd** — get current working directory.

libmega C library (-lmega)

**getcwd()** copies the absolute pathname of the current working directory to the array pointed to by **_buf_**, which is of **_length_** size.

**getwd()** does not malloc(3) any memory. The **_buf_** argument should be a pointer to an array at least **PATH_MAX** bytes long. If the length of the absolute pathname of the current working directory, including the terminating null byte, exceeds **PATH_MAX** bytes, **NULL** is returned, and **_errno_** is set to **ENAMETOOLONG**.

**getcwd()** can fail with the following errors:

* ENAMETOOLONG - The size of the null-terminated absolute pathname string exceeds **PATH_MAX** bytes.

* ERANGE - The **_size_** argument is less than the length of the absolute pathname of the working directory, including the terminating null byte. You need to allocate a bigger array and try again.

None.
