Syntax
int far pascal MFS_OPEN(pszName, pulSize)
Parameters
- pszName
- is a pointer to the ASCIIZ name of the file to be opened. It may include a path but will not include a drive.
- pulSize
- is a pointer to a double word which is filled in by the mini-FSD with the size of the file in bytes.
Returns
If no error is detected, a zero error code is returned. If an error is detected, a non-zero error code is returned.
Sample
char far * pszName; unsigned long far * pulSize; int far pascal MFS_OPEN(pszName, pulSize)
Remarks
Only one file at a time will be opened by this call. The drive will always be the boot drive. The current file position is set to the beginning of the file.
