DCMD_PROF_MAPPING_REM

QNX SDP8.0Devctl and Ioctl CommandsDeveloper

Remove a mapping from a running process

Synopsis:

#include <sys/dcmd_prof.h>

#define DCMD_PROF_MAPPING_REM __DIOT(_DCMD_MISC, PROF_MAPPING_REM, struct __prof_clientinfo)

Arguments to devctl():


Argument	Value
`filedes`	A file descriptor for the profiler that you obtained by opening /dev/profiler.
`dcmd`	DCMD_PROF_MAPPING_REM
`dev_data_ptr`	A pointer to a struct __prof_clientinfo (see DCMD_PROF_ATTACH)
`n_bytes`	`sizeof(struct __prof_clientinfo)`
`dev_info_ptr`	NULL

Description:

This command removes a mapping from a running process.

Input:

Initialize the structure to 0, and then:

Set the cmd member to PROF_CMD_REM_MAPPING, ORing in PROF_CMD_ARCS or PROF_CMD_ARCS_2, depending on the type of arcs (see DCMD_PROF_ATTACH).
Set lowpc and highpc to the low and high addresses for the mapping.

Output:

None.
