getcwd(3)						     Library Functions Manual							 getcwd(3)

NAME

       getcwd - Gets the pathname of the current directory

LIBRARY

       Standard C Library (libc) System V Library (libsysv)

SYNOPSIS

       Standard C Library:

       #include <unistd.h>

       char *getcwd(	  char *buffer,      size_t size);

       System V Library:

       char *getcwd(	  char *buffer,      int size);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       getcwd() - libc version: XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points to a string space to hold the pathname.  Specifies the length of the string space in bytes.  The value of the size parameter must be
       at least the length of the pathname to be returned plus one byte for the terminating null.

DESCRIPTION

       The getcwd() function returns a pointer to a string containing the absolute pathname of the current directory.	The  getwd()  function	is
       called to obtain the pathname.

       [Tru64 UNIX]  If the buffer parameter is a null pointer, the getcwd() function, using the malloc() function, obtains the number of bytes of
       free space as specified by the size parameter.  In this case, the pointer returned by the getcwd() function can be used as the parameter in
       a subsequent call to the free() function.

NOTES

       [Tru64 UNIX]  The getcwd() function is supported for multithreaded applications.

RETURN VALUES

       Upon  successful  completion,  getcwd() returns the buffer parameter.  Otherwise, a null value is returned and errno is set to indicate the
       error.

ERRORS

       The getcwd() function sets errno to the specified values for the following conditions: Read or search permission was denied for a component
       of the pathname.  The size parameter is zero.

	      [Tru64  UNIX]  The  size	parameter is less than or equal to zero (for the libsys5 version of getcwd() only).  The size parameter is
	      greater than zero, but is smaller than the length of the pathname + 1.  The requested amount of memory could not be allocated.
