Hot start file manager — in-memory representation + I/O.
HotStartManager provides the C++ implementation of the hot start API declared in include/openswmm/engine/openswmm_hotstart.h.
V1 (legacy — no infiltration/GW state): Offset Size Field <hr> 0 16 Magic "OPENSWMM_HS_V1\0" 16 4 Version: uint32_t = 1 ... (nodes, links as before) Per-subcatch: [uint32 name_len, char name[], double runoff, double gwater] EOF-4 4 CRC32: uint32_t
V2 (Gap #54 — includes infiltration model state and GW zone state): 0 16 Magic "OPENSWMM_HS_V1\0" (same magic, version byte changes) 16 4 Version: uint32_t = 2 20 8 Timestamp (Unix seconds): int64_t 28 8 Simulation time at save (decimal days): double 36 8 Start date (OADate): double 44 8 End date (OADate): double 52 4 CRS string length: uint32_t 56 n CRS string (null-terminated) 56+n 4 Node count: uint32_t ... ... Per-node: [uint32 name_len, char name[], double depth, double head, double volume] Link count: uint32_t Per-link: [uint32 name_len, char name[], double flow, double depth, double volume] Subcatch count: uint32_t Per-subcatch V2: [uint32 name_len, char name[], double runoff, double gwater, uint32_t infil_model, double infil[6], double gw_theta, double gw_lower_depth] EOF-4 4 CRC32 of all preceding bytes: uint32_t
HotStartFile instances are not thread-safe. The C API wraps each handle with a raw pointer cast; callers are responsible for not sharing handles across threads.
