ls_fdbusy

Tests if a specified file descriptor is in use or reserved by LSF.

ls_fdbusy tests if a specified file descriptor is in use or reserved by LSF. The possible descriptors used by LSF are those used for contacting the LIM and for remote execution. fd is the file descriptor to test. This call is typically used when an application wants to close all unneeded file descriptors.

Any program using this routine must call ls_initrex first.

Any program using this API must be setuid to root if LSF_AUTH is not defined in the lsf.conf file.
