FSH_ADDSHARE(pName, mode, hVPB, phShare)

The name must be in canonical form: no '.' or '. .' components, uppercase, no meta characters, and full path name specified .

mode

is the sharing mode and access mode as defined in the DosOpen API. All other bits (direct open, write-through, etc.) must be zero.

phShare

is the pointer to the location where a share handle is stored. This handle may be passed to FSH_REMOVESHARE.

there is not enough memory to hold sharing information.

• ERROR_INVALID_PARAMETER

path name is too long.

Calling Sequence

int far pascal FSH_ADDSHARE(pName, mode, hVPB, phShare)

char far * pName;
unsigned short mode;
unsigned short hVPB;
unsigned long far * phShare;

Remarks

Do not call FSH_ADDSHARE for character devices.

FSH_ADDSHARE may block.

Note

OS/2 does not validate input parameters. Therefore, an FSD should call FSH_PROBEBUF where appropriate.
