cfg_subsysop(9r)cfg_subsysop(9r)NAMEcfg_subsysop - Kernel routine used to perform subsystem-defined opera‐
tions
SYNOPSIS
#include <sys/sysconfig.h> ); cfg_status_t cfg_subsysop(
char *subsys,
cfg_op_t op,
caddr_t indata,
size_t insize,
caddr_t outdata,
size_t outsize );
ARGUMENTS
Name of the subsystem. Value of the operation code defined by the sub‐
system to be preformed. Subsystem codes are from 100 to 999. The input
data to the subsystem's configure routine. This buffer is allocated by
the caller. Its contents are filled in by the caller. The length of
the data in bytes in the indata argument. The output data of the oper‐
ation. This buffer is allocated by the caller, but its contents are
filled in by the system's configure routine. The length in bytes of
the output data in the output buffer.
DESCRIPTION
The cfg_subsysop( ) routine performs a subsystem defined operation. The
semantics of the operation are defined by the subsystem and implemented
in the subsystem's configure routine.
RETURN VALUES
This routine returns 32 bit status values of type cfg_status_t composed
of subsystem status and framework status segments. The upper 16 bits
is the subsystem status (CFG_STATUS_SUBSYS) and the lower 16 bits is
the frame status (CFG_STATUS_FRAME). The return values are organized as
follows:[Upper subsystem 16 bits][Lower framework 16 bits]
The subsystem status is returned by the subsystem's configure routine
and can be any error in errno.h. The framework status is returned by
the configuration framework and the possible values are defined in
<sys/sysconfig.h> as CFG_FRAME_Exxx. A completely successful operation
has ESUCCESS (0) returned in both status segments.
See the cfg_errno(9r) and errno(2) reference pages for more details
about error numbers and status.
EXAMPLE
char indata[IN_SZ];
char outdata[OUT_SZ];
cfg_status_t retval;
/***************************************************/
/* Call the cfg_subsysop routine */
retval = cfg_subsysop("lvm", CLEAN_UP, indata,IN_SZ, outdata,
OUT_SZ);
if (retval != CFG_SUCCESS)
print_error(retval);
