status = PMDFgetHostName (host, host_len)

argument information

int PMDFgetHostName(char *host, int *host_len)

Arguments

host

String to receive the official local host name. This string should be at least ALFA_SIZE+1 bytes long.

host_len

Length in bytes of the returned host string. Callers using PMDFgetHostName must, on input, supply the maximum length in bytes of host.

Description

The official name of the local host (i.e., the host name associated with the local, l, channel) can be obtained by calling PMDFgetHostName . This host name is typically used when constructing return addresses for local users. Such a return address is simply user@host where user is the name of the local user and host is the local host name.

Return Values

PMDF__OK	Normal, successful completion.
PMDF__FATERRLIB	Call to LIB$SCOPY_R_DX failed owing to a fatal internal error in the OpenVMS Run Time Library. Host name not returned.
PMDF__INSVIRMEM	Insufficient virtual memory: call to LIB$GET_VM made by LIB$SCOPY_R_DX has failed. Host name not returned.
PMDF__INVSTRDES	Invalid string descriptor for host: descriptor has an invalid value in its DSC$B_CLASS field. Host name not returned.
PMDF__STRTRU	Supplied string was too long; value truncated to fit.
