KINFO_GETALLPROC(3)    FreeBSD Library Functions Manual    KINFO_GETALLPROC(3)

NAME
     kinfo_getallproc - function for getting process information of all
     processes from kernel

LIBRARY
     System Utilities Library (libutil, -lutil)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/user.h>
     #include <libutil.h>

     struct kinfo_proc *
     kinfo_getallproc(int *cntp);

DESCRIPTION
     This function is used for obtaining process information of all processes
     from the kernel.

     The cntp field is a pointer containing the number of process structures
     returned.  This function is a wrapper around sysctl(3) with the
     KERN_PROC_PROC mib.  While the kernel returns a packed structure, this
     function expands the data into a fixed record format.

RETURN VALUES
     On success the kinfo_getallproc() function returns a pointer to cntp
     struct kinfo_proc structures as defined by <sys/user.h>.  The pointer was
     obtained by an internal call to malloc(3) and must be freed by the caller
     with a call to free(3).  On failure the kinfo_getallproc() function
     returns NULL.

SEE ALSO
     free(3), malloc(3), sysctl(3)

HISTORY
     The kinfo_getallproc() function first appeared in FreeBSD 8.3.
