/******************************************************************************* * * FUNCTION: AcpiUtStrtoul64 * * PARAMETERS: String - Null terminated input string * Flags - Conversion info, see below * ReturnValue - Where the converted integer is * returned * * RETURN: Status and Converted value * * DESCRIPTION: Convert a string into an unsigned value. Performs either a * 32-bit or 64-bit conversion, depending on the input integer * size in Flags (often the current mode of the interpreter). * * Values for Flags: * ACPI_STRTOUL_32BIT - Max integer value is 32 bits * ACPI_STRTOUL_64BIT - Max integer value is 64 bits * ACPI_STRTOUL_BASE16 - Input string is hexadecimal. Default * is 10/16 based on string prefix (0x). * * NOTES: * Negative numbers are not supported, as they are not supported by ACPI. * * Supports only base 16 or base 10 strings/values. Does not * support Octal strings, as these are not supported by ACPI. * * Current users of this support: * * Interpreter - Implicit and explicit conversions, GPE method names * Debugger - Command line input string conversion * iASL - Main parser, conversion of constants to integers * iASL - Data Table Compiler parser (constant math expressions) * iASL - Preprocessor (constant math expressions) * AcpiDump - Input table addresses * AcpiExec - Testing of the AcpiUtStrtoul64 function * * Note concerning callers: * AcpiGbl_IntegerByteWidth can be used to set the 32/64 limit. If used, * this global should be set to the proper width. For the core ACPICA code, * this width depends on the DSDT version. For iASL, the default byte * width is always 8 for the parser, but error checking is performed later * to flag cases where a 64-bit constant is defined in a 32-bit DSDT/SSDT. * ******************************************************************************/
