Control Open HFS File Descriptors

Portability: SAS/C extension


DESCRIPTION


DESCRIPTION

_fcntl is a version of fcntl designed to operate only on USS files. _fcntl runs faster and calls fewer other library routines than fcntl . The _fcntl function is used exactly like the standard fcntl function. The first argument to _fcntl must be the file descriptor for an open HFS file. Refer to fcntl for a full description.
