Routine Description:
|
|
|
|
This function locates an environment variable and returns its value.
|
|
|
|
Arguments:
|
|
|
|
Variable - Supplies a pointer to a zero terminated environment variable
|
|
name.
|
|
|
|
Length - Supplies the length of the value buffer in bytes.
|
|
|
|
Buffer - Supplies a pointer to a buffer that receives the variable value.
|
|
|
|
Return Value:
|
|
|
|
ESUCCESS is returned if the enviroment variable is located. Otherwise,
|
|
ENOENT is returned.
