| word32 | CheckRunTimeFastMath(void ) This function checks the runtime fastmath settings for the maximum size of an integer. It is important when a user is using a wolfCrypt library independently, as the FP_SIZE must match for each library in order for math to work correctly. This check is defined as CheckFastMathSettings(), which simply compares CheckRunTimeFastMath and FP_SIZE, returning 0 if there is a mismatch, or 1 if they match. |

word32 CheckRunTimeFastMath( void )This function checks the runtime fastmath settings for the maximum size of an integer. It is important when a user is using a wolfCrypt library independently, as the FP_SIZE must match for each library in order for math to work correctly. This check is defined as CheckFastMathSettings(), which simply compares CheckRunTimeFastMath and FP_SIZE, returning 0 if there is a mismatch, or 1 if they match.
Parameters:
- none No parameters.
Return: FP_SIZE Returns FP_SIZE, corresponding to the max size available for the math library.
Example
if (CheckFastMathSettings() != 1) {return err_sys("Build vs. runtime fastmath FP_MAX_BITS mismatch\n");}// This is converted by the preprocessor to:// if ( (CheckRunTimeFastMath() == FP_SIZE) != 1) {// and confirms that the fast math settings match// the compile time settingsSource code
