NAME sam_mig_stage_write - Stages data from foreign data migra- tion program SYNOPSIS cc [ flag ... ] file ... -L/opt/SUNWsamfs/lib -lsamut [ library ... ] #include "/opt/SUNWsamfs/include/mig.h" int sam_mig_stage_write(tp_stage_t *stage_req, char *buffer, int len, offset_t offset); AVAILABILITY SUNWsamfs DESCRIPTION sam_mig_stage_write() passes data from the foreign data migration program to the file system for the stage associ- ated with stage_req (see sam_mig_stage_file(3)). stage_req is the number of this stage request. buffer is a pointer to the data that needs to be transferred. len is the number of bytes of data to transfer. offset is the offset from the beginning of this stage request. This is not the offset from the beginning of the file (keep in mind stage_never). RETURN VALUES sam_mig_stage_write returns the actual number of bytes writ- ten. Otherwise, a value of -1 is returned. If an error is returned, sam_mig_stage_end should still be called. The only function allowed on stage_req after an error is sam_mig_stage_end.
