/* MODULE HTAAUtil.c
|
||
|
|
** COMMON PARTS OF ACCESS AUTHORIZATION MODULE
|
||
|
|
** FOR BOTH SERVER AND BROWSER
|
||
|
|
**
|
||
|
|
** IMPORTANT:
|
||
|
|
** Routines in this module use dynamic allocation, but free
|
||
|
|
** automatically all the memory reserved by them.
|
||
|
|
**
|
||
|
|
** Therefore the caller never has to (and never should)
|
||
|
|
** free() any object returned by these functions.
|
||
|
|
**
|
||
|
|
** Therefore also all the strings returned by this package
|
||
|
|
** are only valid until the next call to the same function
|
||
|
|
** is made. This approach is selected, because of the nature
|
||
|
|
** of access authorization: no string returned by the package
|
||
|
|
** needs to be valid longer than until the next call.
|
||
|
|
**
|
||
|
|
** This also makes it easy to plug the AA package in:
|
||
|
|
** you don't have to ponder whether to free() something
|
||
|
|
** here or is it done somewhere else (because it is always
|
||
|
|
** done somewhere else).
|
||
|
|
**
|
||
|
|
** The strings that the package needs to store are copied
|
||
|
|
** so the original strings given as parameters to AA
|
||
|
|
** functions may be freed or modified with no side effects.
|
||
|
|
**
|
||
|
|
** The AA package does not free() anything else than what
|
||
|
|
** it has itself allocated.
|
||
|
|
**
|
||
|
|
** AA (Access Authorization) package means modules which
|
||
|
|
** names start with HTAA.
