getwd(S)

getwd -- get current working directory pathname

Synopsis

   #include <unistd.h>
   
   char *getwd(char *path_name);

Description

The getwd function determines an 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, then getwd fails and returns a NULL pointer. (See limits(F) for a description of PATH_MAX.)

Return value

Upon successful completion, a pointer to the string containing the absolute pathname of the current working directory is returned. Otherwise, getwd returns a NULL pointer and the contents of the array pointed to by path_name are undefined.

Compatibility

For portability to earlier implementations of the UNIX^® system, getcwd(S) is preferred over this function.
