KINFO_GETPROC(3)					   BSD Library Functions Manual 					  KINFO_GETPROC(3)

NAME

     kinfo_getproc -- function for getting process information from kernel

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

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

     struct kinfo_proc *
     kinfo_getproc(pid_t pid);

DESCRIPTION

     This function is used for obtaining process information from the kernel.

     The pid field contains the process identifier.  This should be a process that you have privilege to access.  This function is a wrapper
     around sysctl(3) with the KERN_PROC_PID mib.  While the kernel returns a packed structure, this function expands the data into a fixed record
     format.

RETURN VALUES

     On success the kinfo_getproc() function returns a pointer to a struct kinfo_proc structure 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_getproc() function
     returns NULL.

NAME

     kinfo_getvmmap -- function for getting per-process memory map information

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

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

     struct kinfo_vmentry *
     kinfo_getvmmap(pid_t pid, int *cntp);

DESCRIPTION

     This function is used for obtaining virtual memory mapping information of a particular process.

     The pid field contains the process identifier.  This should be the a process that you have privilege to access.  The cntp field is allows the
     caller to know how many records are returned.

     This function is a wrapper around sysctl(3) with the KERN_PROC_VMMAP mib.	While the kernel returns a packed structure, this function expands
     the data into a fixed record format.

RETURN VALUES

     On success the kinfo_getvmmap() function returns a pointer to an array of struct kinfo_vmentry structures as defined by <sys/user.h>.  The
     array 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_getvmmap()
     function returns NULL.
