int vxfs_ap_query_ckpt(int fd, char *ckptname, char *datapol, char *metapol);
vxfs_ap_query_ckpt() retrieves information about the Storage Checkpoint allocation policies assigned to the given Storage Checkpoint. The datapol and metapol arguments must point to buffers of (FSAP_NAMESZ + 1) bytes, which are filled in with the name of the policy (if any) and NULL-terminated. If no policy is assigned, the string "NONE" is returned. datapol is the name of the data policy that can be created with fsapadm(1M) or through the vxfs_ap_defined() API. metapol is the name of the metadata policy that can be created with fsapadm(1M) or through the vxfs_ap_define() API. The file descriptor fd specifies a file within the Storage Checkpoint.
To use this function, specify -l vxfsutil while linking. Specify the /opt/VRTSvxfs/lib directory for 32-bit executables, or the /opt/VRTSvxfs/lib/sparcv9 directory for 64-bit executables.
This function is supported only on Version 6 and later disk layouts. This API supports file system versions 6.0 and above.
vxfs_ap_query_ckpt() returns zero on success, non-zero on failure.
The file system is not currently frozen.
One or more of the specified pointer arguments points to an illegal address.
An was made to reserve space larger than the maximum file size for this process.
The command or argument is invalid.
An I/O error occurred during the operation.
One or more of the named policies does not exist.
There is no license installed to allow this operation.
This operation is not supported by the disk layout version of the specified file system. Use vxupgrade(1m) to enable this operation.
There is no such device or address.
The effective user ID of the calling process does not have appropriate privileges to perform this operation.
