Detailed Description

Management of system environment variables An environment variable is composed of a variable name and its value.

To be portable among various systems, environment variables are local to a process.

Member Function Documentation

◆ Build()

void OSD_Environment::Build ( )

Sets the value of an environment variable into system (physically).

◆ Error()

Standard_Integer OSD_Environment::Error ( ) const

Returns error number if 'Failed' is TRUE.

◆ Failed()

Standard_Boolean OSD_Environment::Failed ( ) const

Returns TRUE if an error occurs.

◆ Name()

TCollection_AsciiString OSD_Environment::Name ( ) const

Gets the name of <me>.

◆ Perror()

void OSD_Environment::Perror ( )

Raises OSD_Error.

◆ Remove()

void OSD_Environment::Remove ( )

Removes (physically) an environment variable.

◆ Reset()

void OSD_Environment::Reset ( )

Resets error counter to zero.

◆ SetName()
