Detailed Description

Implements the OP_PCSC_ESTABLISH opcode (conditional build).

Creates a new PC/SC context using SCardEstablishContext(SCARD_SCOPE_SYSTEM) and registers it in the internal PCSC context registry when FUN_WITH_PCSC is enabled. Returns the allocated context id on success, or 0 on failure. When PCSC support is disabled at build time, this opcode returns 0.

OP_PCSC_ESTABLISH: () -> int

• Returns: context id (>0) on success; 0 on error or when disabled.
