CopyOutDParam
void CopyOutDParam(std::vector< StringParameterBackup > &backup, size_t num)
Copy num string parameters from the global string parameter array to the backup.
Definition: strings.cpp:176
SetDParam
void SetDParam(size_t n, uint64_t v)
Set a string parameter v at index n in the global string parameter array.
Definition: strings.cpp:104
HaveDParamChanged
bool HaveDParamChanged(const std::vector< StringParameterBackup > &backup)
Checks whether the global string parameters have changed compared to the given backup.
Definition: strings.cpp:194
SetDParamStr
void SetDParamStr(size_t n, const char *str)
