fchdir()

Change the working directory

Synopsis:

#include <unistd.h>

int fchdir(int fd);

Since:

BlackBerry 10.0.0

Arguments:

var
A file descriptor for the directory that you want to become the current working directory.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The fchdir() function is similar to chdir(), except that you use a file descriptor to specify the directory that you want to become the new current working directory. You can obtain a file descriptor for a directory by calling open(), provided that the file status flags and access modes don't contain O_WRONLY or O_RDWR.

Returns:

0, or -1 if an error occurred ( errno is set). If the function fails, the current working directory isn't changed.

Errors:

EACCES
Search permission is denied for the directory referenced by fd.
EBADF
The fd argument isn't an open file descriptor.
ENOTDIR
The open file descriptor fd doesn't refer to a directory.
EINTR
A signal was caught during the execution of fchdir().
EIO
An I/O error occurred while reading from or writing to the filesystem.

Classification:

POSIX 1003.1 XSI

Safety:  
Cancellation point No
Interrupt handler No
Signal handler Yes
Thread Yes
