NAME

chdir − change working directory

SYNOPSIS

int chdir (path)
char ∗path;

DESCRIPTION

Path points to the path name of a directory.  Chdir causes the named directory to become the current working directory, the starting point for path searches for path names not beginning with /. 

ERRORS

Chdir will fail and the current working directory will be unchanged if one or more of the following are true:

­[ENOTDIR] A component of the path name is not a directory. 

­[ENOENT] The named directory does not exist. 

­[EACCES] Search permission is denied for any component of the path name. 

­[EFAULT] Path points outside the allocated address space of the process.  The reliable detection of this error will be implementation dependent. 

­[ENOENT] Path is null. 

­[ENAMETOOLONG] The named directory exceeds MAXPATHLEN characters. 

RETURN VALUE

Upon successful completion, a value of 0 is returned.  Otherwise, a value of −1 is returned and errno is set to indicate the error.
