SYNOPSIS

#include <sys/version.h>

#define VERSIONLEN 32
 struct version {
unsignedv_id   : 20,/∗ Object id for identifying program ∗/
v_iver : 12;/∗ Internal version number ∗/
charv_version[VERSIONLEN];/∗ Version string for humans ∗/
};
 cc = getversion(buffer, bufsize)
int cc;
struct version ∗buffer;
int nbytes;

DESCRIPTION

getversion returnes the kernel version structure to the given buffer, at most bufsize bytes are copied. The v_id and v_iver are the numbers used by the versioning system, v_id is 1, and v_iver is unique for all released kernels. The v_version array contains the string printed when the kernel boots. 

RETURN VALUE

If the call succeeds a value of 0 is returned.  If the call fails, then a value of −1 is returned and an error code is placed in the global location errno.
