chdir(2) | System Calls Manual | chdir(2) |
NAME¶
chdir, fchdir - change working directory
LIBRARY¶
Standard C library (libc, -lc)
SYNOPSIS¶
#include <unistd.h>
int chdir(const char *path); int fchdir(int fd);
fchdir():
_XOPEN_SOURCE >= 500
|| /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
|| /* glibc up to and including 2.19: */ _BSD_SOURCE
DESCRIPTION¶
chdir() changes the current working directory of the calling process to the directory specified in path.
fchdir() is identical to chdir(); the only difference is that the directory is given as an open file descriptor.
RETURN VALUE¶
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
ERRORS¶
Depending on the filesystem, other errors can be returned. The more general errors for chdir() are listed below:
- EACCES
- Search permission is denied for one of the components of path. (See also path_resolution(7).)
- EFAULT
- path points outside your accessible address space.
- EIO
- An I/O error occurred.
- ELOOP
- Too many symbolic links were encountered in resolving path.
- ENAMETOOLONG
- path is too long.
- ENOENT
- The directory specified in path does not exist.
- ENOMEM
- Insufficient kernel memory was available.
- ENOTDIR
- A component of path is not a directory.
The general errors for fchdir() are listed below:
STANDARDS¶
POSIX.1-2008.
HISTORY¶
POSIX.1-2001, SVr4, 4.4BSD.
NOTES¶
The current working directory is the starting point for interpreting relative pathnames (those not starting with '/').
A child process created via fork(2) inherits its parent's current working directory. The current working directory is left unchanged by execve(2).
