Manual page for CHDIR(2)
chdir - change current working directory
SYNOPSIS
int chdir(const char *path);
DESCRIPTION
The
chdir
function causes the directory
indicated by
path
to become the current working directory;
that is, the starting point assumed
for pathnames not beginning with ``/''.
If the
chdir
function fails, the current working directory is left unchanged.
In order for a directory to become the current directory,
a process must have execute (search) access to the directory.
RETURN VALUE
Upon successful completion,
chdir
returns a value of 0.
Otherwise, a value of -1 is returned and
errno
is set to indicate
the error.
