The following error is received:

.\crypt_protect.c: In function 'main':
.\crypt_protect.c:31:34: error: 'CRYPTPROTECT_PROMPT_ON_PROTECT' undeclared (first use in this function)
PromptStruct.dwPromptFlags = CRYPTPROTECT_PROMPT_ON_PROTECT;
^
.\crypt_protect.c:31:34: note: each undeclared identifier is reported only once for each function it appears in

The needed CRYPTPROTECT_PROMPT_ON_PROTECT should be defined in wincrypt.h according to:
