Subject: [PATCH] CryptoPkg/CrtLib: add access/open/read/write/close syscalls
|
|
|
|
Needed by rhel downstream openssl patches, they use unix syscalls
|
|
for file access (instead of fopen + friends like the rest of the
|
|
code base). No actual file access is needed for edk2, so just
|
|
add stubs to make linking work.
