KINFO_GETVMMAP(3) NetBSD Library Functions Manual KINFO_GETVMMAP(3)
kinfo_getvmmap -- function for getting per-process memory map information
System Utilities Library (libutil, -lutil)
#include <sys/types.h> #include <sys/sysctl.h> #include <util.h> struct kinfo_vmentry * kinfo_getvmmap(pid_t pid, size_t *cntp);
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.
On success the kinfo_getvmmap() function returns a pointer to an array of struct kinfo_vmentry structures as defined by <sys/sysctl.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.
