GETWD(3) Library Functions Manual GETWD(3)

NAME

getwd — get the 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, getwd() fails and returns a null pointer.

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.

ERRORS

No errors are defined.

EXAMPLES

None.

APPLICATION USAGE

For portability to implementations conforming to earlier versions of this specification, getcwd(3) is preferred over this function.

FUTURE DIRECTIONS

None.
