ParseUserFriendlySizeExpression()

std::optional< uint64_t > lldb_private::trace_intel_pt::ParsingUtils::ParseUserFriendlySizeExpression

(

llvm::StringRef

size_expression

)

Convert an integral size expression like 12KiB or 4MB into bytes.

The units are taken loosely to help users input sizes into LLDB, e.g. KiB and KB are considered the same (2^20 bytes) for simplicity.

Parameters

[in]

size_expression

String expression which is an integral number plus a unit that can be lower or upper case. Supported units: K, KB and KiB for 2^10 bytes; M, MB and MiB for 2^20 bytes; and B for bytes. A single integral number is considered bytes.

Returns

The converted number of bytes or std::nullopt if the expression is invalid.
