NAME

getcwd, gethcwd − get path-name of current working directory

SYNOPSIS

char ∗getcwd (buf, size)
char ∗buf;
int size;
char *gethcwd (buf, size)
char *buf;
int size;

DESCRIPTION

Getcwd returns a pointer to the current directory path-name.  The value of size must be at least two greater than the length of the path-name to be returned. 

If buf is a NULL pointer, getcwd will obtain size bytes of space using malloc(3C). In this case, the pointer returned by getcwd may be used as the argument in a subsequent call to free (see malloc(3C)).

DIAGNOSTICS

Returns NULL with errno set if size is not large enough, or if an error ocurrs in a lower-level function. 

EXAMPLES

char ∗cwd, ∗getcwd();
.
.
.
if ((cwd = getcwd((char ∗)NULL, 64)) == NULL) {

perror("pwd");
exit(1);

}
printf("%s\n", cwd);

DEPENDENCIES

Series 300 Diskless
Gethcwd works the same as getcwd except the returned directory path name will list all hidden directories (context dependent files, see cdf(4)).
