- NAME
- GetEnv -- Get the value of an environment variable
-
- SYNOPSIS
- strptr = Getenv("string", buffer, size)
- d0 A0 A1 d0
-
- FUNCTION
- This function provides an environment variable mechanism
- compatible with MANX. Note that this call is more efficient
- than using the manx getenv() function call when arplibrary
- is installed.
-
- INPUTS
- string -- pointer to an environment variable name.
-
- buffer -- a user allocated area which will be used to store
- the value associated with the environment variable.
- This may be NULL.
-
- size -- size of buffer region in bytes.
-
- RESULT
- If found, a pointer to the start of the value string for
- that variable will be returned. If buffer is non-null, then
- as much of the value string as allowed by size will be
- copied into the user buffer.
-
- ADDTIONAL CONSIDERATIONS
- arp.libraries environment variable mechanism is compatible
- with the MANX software, which has set the defacto standard
- implementation for the Amiga. This call is NOT equivalent
- to the Manx getenv() call, however.
-
- You should run as Forbidden() any code that uses or examines
- the return value from this function, which is a pointer to
- the global environment space of ArpLib.
-
- BUGS
- None Known.
