getwd()

Get current working directory pathname

Synopsis:

#include <unistd.h>

char* getwd( char*  path_name );

Library:

libc

Description:

The getwd() function determines the absolute pathname of the current working directory of the calling process, and copies that pathname into the array pointed to by the path_name argument.

If the length of the pathname of the current working directory is greater than ({PATH_MAX} + 1) including the null byte, getwd() fails and returns a null pointer.

For portability, use getcwd() instead of getwd().

Returns:

A pointer to the string containing the absolute pathname of the current working directory. On error, getwd() returns a null pointer and the contents of the array pointed to by path_name are undefined.

Classification:
