.Sh NAME
.Nm procmap
.Nd print a procfs map file
.Sh SYNOPSIS
.Nm procmap
.Ar <pid>
.Nm procmap
curproc
.Sh DESCRIPTION
The
.Nm
utility prints the full contents of a procfs map file.
Using a program such as cat is unreliable for this purpose, since the kernel
must be able to write the entire contents at once, which requires a sufficiently
large buffer.
.Sh FILES
/proc/*/map
.Sh SEE ALSO
.Xr procfs 5
