Data Java PMC help

May I know how to add space in the email body for PMC using java?

How do we ignore case of the headers?

And also, how to create message class to store the data?

PMC_ATTACH(3)						   BSD Library Functions Manual 					     PMC_ATTACH(3)

NAME
pmc_attach, pmc_detach -- attaching and detaching process scope PMCs to target processes LIBRARY
Performance Counters Library (libpmc, -lpmc) SYNOPSIS
#include <pmc.h> int pmc_attach(pmc_id_t pmcid, pid_t pid); int pmc_detach(pmc_id_t pmcid, pid_t pid); DESCRIPTION
These functions control the set of target processes tracked by a process scope PMC. Function pmc_attach() is used to attach a process scope PMC specified by argument pmcid to a target process specified by argument pid. Argu- ment pid may be zero to denote the current process. If the PMC was allocated with modifier PMC_F_DESCENDANTS, the PMC will additionally attach to current and future descendents of the specified target process. The PMC should be in a quiescent state (i.e., not running). Function pmc_detach() is used to detach a process scope PMC specified by argument pmcid from a process specified by argument pid. Argument pid may be zero to denote the current process. RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error. ERRORS
A call to function pmc_attach() may fail with the following errors: [EBUSY] Argument pmcid specified a PMC that was not in a quiescent state. [EBUSY] The target process specified by function pmc_attach is being tracked by another process scope PMC that uses the same PMC hardware resources. [EEXIST] The target process is already being tracked by the specified PMC. [EINVAL] Argument pmcid specified a PMC with system scope. [EINVAL] Argument pid specified an illegal process id. [EINVAL] The current process does not own a PMC with the handle specified in argument pmcid. [EPERM] The caller lacked the privilege needed to attach PMCs to the specified target process. [EPERM] (i386 and amd64 architectures) The PMC specified by argument pmcid has been setup to allow the use of the RDPMC instruc- tion for self measurement. [ESRCH] The current process does not own any PMCs. [ESRCH] The process specified by argument pid did not exist. A call to function pmc_detach() may fail with the following errors: [EINVAL] Argument pmcid specified a PMC with system scope. [EINVAL] Argument pid specified an illegal process id. [EINVAL] The current process does not own a PMC with the handle specified in argument pmcid. [EINVAL] The specified PMC was not attached to the target process. [ESRCH] The current process does not own any PMCs. [ESRCH] The process specified by argument pid is not being monitored by hwpmc(4). [ESRCH] The process specified by argument pid did not exist.
