NAME
chdir, fchdir - change working directory SYNOPSIS
#include
int chdir(const char *path); int fchdir(int fd); Feature Test Macro Requirements for glibc (see featuretestmacros(7)): fchdir(): BSDSOURCE || XOPENSOURCE >= 500 || XOPENSOURCE && XOPENSOURCEEXTENDED || /* Since glibc 2.12: */ POSIXCSOURCE >= 200809L 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 appropriately. ERRORS 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 pathresolution(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. CONFORMING TO
SVr4, 4.4BSD, POSIX.1-2001. 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 work‐ ing directory. The current working directory is left unchanged by execve(2).
