.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
