getwd - get the current working directory pathname (
LEGACY)
Návod, kniha: POSIX Programmer's Manual
#include <unistd.h>
char *getwd(char *
path_name);
The
getwd() function shall determine an absolute pathname of the current
working directory of the calling process, and copy a string containing that
pathname into the array pointed to by the
path_name argument.
If the length of the pathname of the current working directory is greater than
({PATH_MAX}+1) including the null byte,
getwd() shall fail and return a
null pointer.
Upon successful completion, a pointer to the string containing the absolute
pathname of the current working directory shall be returned. Otherwise,
getwd() shall return a null pointer and the contents of the array
pointed to by
path_name are undefined.
No errors are defined.
The following sections are informative.
None.
For applications portability, the
getcwd() function should be used to
determine the current working directory instead of
getwd().
Since the user cannot specify the length of the buffer passed to
getwd(),
use of this function is discouraged. The length of a pathname described in
{PATH_MAX} is file system-dependent and may vary from one mount point to
another, or might even be unlimited. It is possible to overflow this buffer in
such a way as to cause applications to fail, or possible system security
violations.
It is recommended that the
getcwd() function should be used to determine
the current working directory.
This function may be withdrawn in a future version.
