A number of CSF have been implemented to be executed asynchronously. This means the CSF call launches a job which will be executed in background while the user program is executed in parallel. This also implies that the CSF has to be called again with the same parameters until the job is finished. As long as the job is not finished, the CSF call will return a dedicated error code (CSF_FS_AS_JOBNOTFIN- ISHED). If another asynchronous CSF call is issued while the previous job is not finished, the CSF call will return (CSF_FS_AS_JOBBUSY).These asynchronous CSF have the form S.File.AS<Name>, whereas the same CSF coded synchronously have the form S.File.<Name>.Two other functions where already provided to be asynchronous. The S.File.For- matFS and S.File.CompressFS which are handled as background job within the file system itself.An asynchronous job is launched by the CSF call with a defined set of parameters. The same call shall be issued later with the same parameter set. For example:CSF
