sr64 subcommand
The sr64 subcommand displays segment registers for a 64-bit process.
Format
sr64 [-g] [-p pid] [esid] [size]
Parameters
| Item | Description |
|---|---|
| -p pid | Specifies the process ID of a 64-bit process. This must be a decimal or hexadecimal value, depending on the setting of the hexadecimal_wanted switch. The hexadecimal_wanted switch is changed using the set subcommand. |
| -g | Displays esids from the global system address space. |
| esid | Specifies the first segment register to display. Register numbers lower than the specified register are ignored. This parameter must be a hexadecimal value. |
| size | Specifies the value to be added to the first segment register to determine the last segment register to display. This parameter must be a hexadecimal value. |
If no parameters are specified, the current process is used. Another process can be specified by using the -p pid flag. Additionally, the esid and size parameters can be used to limit the segment registers displayed. The esid value determines the first segment register to display. The value of esid + size determines the last segment register to display.
The registers are displayed in groups of 16. If necessary,
the value of the esid parameter is rounded
down to a multiple of 16, and the size is
rounded up to a multiple of 16. For example: sr64 11 11 displays the segment registers 10 through 2f.
