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.

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