vxfs_ap_assign_file - assign an allocation policy for file data and metadata
cc -I /opt/VRTS/include -L /opt/VRTS/lib

int vxfs_ap_assign_file(int fd, char *datapol, char *metapol, uint32_t flags);
vxfs_ap_assign_file() assigns the given allocation policies for data and metadata to the file specified by fd. The datapol field specifies an existing data policy. The metapol field specifies an existing metadata policy. To clear a policy assignment, specify a NULL pointer for the policy field to be cleared (either datapol or metapol).
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.
Assigning or defining an allocation policy can fail because of a conflict with volume flags. The conflict detection attempts to detect all conflicts, but there is no guarantee that all conflicts will be detected.
This API supports file system versions 6.0 and above.
Files created in the directory specified by fd inherit the directory's policy assignments.
vxfs_ap_assign_file() returns zero on success, non-zero on failure.
One or more of the specified pointer arguments points to an illegal address.
The calling function issued a request with a file offset off past the EOF mark.
The specified flags are invalid.
An I/O error occurred during the operation.
One or more of the specified 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.
An I/O error occurred during the operation.
The effective user ID of the calling process does not have appropriate privileges to perform this operation.
The specified file system is mounted read-only.
