GetAllNames class methods

Project: Environment Variables Unit

Unit: PJEnvVars

Class: TPJEnvironmentVars

Applies to: ~>3.0

class procedure GetAllNames(const Names: TStrings); overload;
class function GetAllNames: TStringDynArray; overload;

Description

There are two overloads of GetAllNames. Both of them get a list of the names of all environment variables in the current process and return it to the user. The overloads differ in how the names are returned.

TStrings overload

class procedure GetAllNames(const Names: TStrings); overload;

This method returns the environment variable names in the given string list.

Parameters:

• Names – Reference to a string list object that will receive the environment variable names. Any previous contents are discarded. Names must not be nil.

TStringDynArray overload

class function GetAllNames: TStringDynArray; overload;

This form of the method returns an array of environment variable names.

Returns:

• A TStringDynArray dynamic array of strings containing the environment variable names.

TStringDynArray is defined as array of string in Delphi 6 and later. As a convenience to Delphi 5 and earlier users, PJEnvVars defines TStringDynArray when compiled with those compilers.
