Get current working directory pathname
#include <unistd.h>
char* getwd( char *path_name );
- path_name
- A buffer where the function can store the current working directory.
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
|
This function is in libc.a, but not in libc.so
(in order to save space). |
The getwd() function determines the absolute pathname of the
current working directory of the calling process, and copies
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() fails and returns a null pointer.
|
For portability, use getcwd()
instead of getwd(). |
A pointer to the string containing the absolute pathname of the current
working directory. On error, getwd() returns a null pointer and
the contents of the array pointed to by path_name are undefined.
