.Dd July 9, 2009 .Dt KINFO_GETALLPROC 3 .Os .Sh NAME .Nm kinfo_getallproc .Nd function for getting process information of all processes from kernel .Sh LIBRARY .Lb libutil .Sh SYNOPSIS n sys/types.h n libutil.h .Ft struct kinfo_proc * .Fn kinfo_getallproc "int *cntp" .Sh DESCRIPTION This function is used for obtaining process information of all processes from the kernel.

p The .Ar cntp field is a pointer containing the number of process structures returned. This function is a wrapper around .Xr sysctl 3 with the .Dv KERN_PROC_PROC mib. While the kernel returns a packed structure, this function expands the data into a fixed record format. .Sh RETURN VALUES On success the .Fn kinfo_getallproc function returns a pointer to .Ar cntp .Vt struct kinfo_proc structures as defined by n sys/user.h . The pointer was obtained by an internal call to .Xr malloc 3 and must be freed by the caller with a call to .Xr free 3 . On failure the .Fn kinfo_getallproc function returns .Dv NULL . .Sh SEE ALSO .Xr free 3 , .Xr malloc 3 , .Xr sysctl 3
