#include <unistd.h>
The fchdir() system call causes the directory referenced by fd to become the current working directory, the starting point for path searches of pathnames not beginning with a slash, ‘/’.
In order for a directory to become the current directory, a process must have execute (search) access to the directory.
[ENOTDIR] | |
A component of the path prefix is not a directory. | |
[ENAMETOOLONG] | |
A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. | |
[ENOENT] | |
The named directory does not exist. | |
[ELOOP] | |
Too many symbolic links were encountered in translating the pathname. | |
[EACCES] | |
Search permission is denied for any component of the path name. | |
[EFAULT] | |
The path argument points outside the process's allocated address space. | |
[EIO] | An I/O error occurred while reading from or writing to the file system. |
[EINTEGRITY] | |
Corrupted data was detected while reading from the file system. | |
The fchdir() system call will fail and the current working directory will be unchanged if one or more of the following are true:
[EACCES] | |
Search permission is denied for the directory referenced by the file descriptor. | |
[ENOTDIR] | |
The file descriptor does not reference a directory. | |
[EBADF] | |
