linx_get_stat() - Get the statistics of a LINX endpoint
linx_free_stat() - Free the statistics struct returned by linx_get_stat(3)

Synopsis

#include <linx_types.h>
#include <linx_ioctl.h>
#include <linx.h>

int linx_get_stat(LINX *linx, LINX_SPID spid, struct linx_info_stat **stat);

int linx_free_stat(LINX *linx, struct linx_info_stat **stat);

Description

Get the statistics of the LINX endpoint, associated with the local spid binary identifier if the LINX kernel module is compiled with SOCK_STAT=yes.

linx is the handle to the LINX endpoint, which is used to retrive the statistics.

spid is the identifier of the other LINX endpoint, for which the statistics is requested.

stat will on return point to an struct linx_info_stat buffer contining the statistics. Unless returned as NULL, the buffer must be freed by the user with linx_free_stat(3) , when no longer needed. For details on the linx_info_stat struct see linx(7) .

Return Value

Returns 0 if successful, for linx_get_stat(3) the stat will contain a pointer to a buffer, allocated by LINX, containing the statistics. The user is responsible for freeing the buffer with linx_free_stat(3) .
In case of failure, -1 will be returned and errno will be set.

Errors

ENOSYS if the LINX kernel module has not been compiled with SOCK_STAT=yes.

ENOMEM Insufficient memory is available.

EBADF The linx handle is associated with an invalid socket descriptor.

Bugs/Limitations

None.
