Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
fchdir():
Since glibc 2.12:
_BSD_SOURCE || _XOPEN_SOURCE >= 500 || _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED || _POSIX_C_SOURCE >= 200809L
Before glibc 2.12:
_BSD_SOURCE || _XOPEN_SOURCE >= 500 _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
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.
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.
Depending on the file system, 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 file 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:
EACCES |
Search permission was denied on the directory open on fd. | ||
EBADF |
fd is not a valid file descriptor. |
SVr4, 4.4BSD, POSIX.1-2001.
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).
The prototype for fchdir() is only available if _BSD_SOURCE is defined, or _XOPEN_SOURCE is defined with the value 500.
