Gets current directory path name.
char *getwd ( PathName)
char *PathName;
The getwd subroutine determines the absolute path name of the current directory, then copies that path name into the area pointed to by the PathName parameter.
The maximum path-name length, in characters, is set by the PATH_MAX value, as specified in the limits.h file.
| PathName | Points to the full path name. |
If the call to the getwd subroutine is successful, a pointer to the absolute path name of the current directory is returned. If an error occurs, the getwd subroutine returns a null value and places an error message in the PathName parameter.
This subroutine is part of Base Operating System (BOS) Runtime.
The getcwd (getcwd Subroutine) subroutine.
