- Parameters
-
| [in] | *filename | Filename to be opened |
| [in] | *envvar | Unix/MS-DOS environment variable Other OS assign name (with :) |
| [in] | *mode | Mode in which to open file (r, w, etc) |
| [out] | *noenv | Set to TRUE under Unix/MS-DOS if the reason for failure was that the environment variable was not set. |
- Returns
- File pointer or NULL on failure
Attempts to open a filename as specified. Returns a file pointer. If this fails:
Under UNIX/MS-DOS: gets the contents of the envvar environment variable and prepends that to the filename and tries again. If envvar was not set, noenv is set to TRUE and the routine returns a NULL pointer.
Under other OSs: prepends the envvar string onto the filename and tries to open the file again.
Returns the pointer returned by the open() command after all this.
