* NAME
|
|
* tls_level 3
|
|
* SUMMARY
|
|
* TLS security level conversion
|
|
* SYNOPSIS
|
|
* #include <tls.h>
|
|
*
|
|
* int tls_level_lookup(name)
|
|
* const char *name;
|
|
*
|
|
* const char *str_tls_level(level)
|
|
* int level;
|
|
* DESCRIPTION
|
|
* The macros in this module convert TLS levels from symbolic
|
|
* name to internal form and vice versa. The macros are safe
|
|
* because they evaluate their arguments only once.
|
|
*
|
|
* tls_level_lookup() converts a TLS level from symbolic name
|
|
* to internal form. When an unknown level is specified,
|
|
* tls_level_lookup() logs no warning, and returns TLS_LEV_INVALID.
|
|
*
|
|
* str_tls_level() converts a TLS level from internal form to
|
|
* symbolic name. The result is a null pointer for an unknown
|
|
* level.
