chdir - change working directory


#include <unistd.h>

int chdir(const char *path);


The chdir() function causes the directory named by the pathname pointed to by the path argument to become the current working directory; that is, the starting point for path searches for pathnames not beginning with /.


Upon successful completion, 0 is returned. Otherwise, -1 is returned, the current working directory remains unchanged and errno is set to indicate the error.


The chdir() function will fail if:
Search permission is denied for any component of the pathname.
Too many symbolic links were encountered in resolving path.
The path argument exceeds {PATH_MAX} in length or a pathname component is longer than {NAME_MAX}.
A component of path does not name an existing directory or path is an empty string.
A component of the pathname is not a directory.

The chdir() function may fail if:

Pathname resolution of a symbolic link produced an intermediate result whose length exceeds {PATH_MAX}.
