KINFO_GETALLPROC(3) BSD 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 <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

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. SEE ALSO
