const ssize_t ChunkSize = 4096*4;
SmallString<ChunkSize> Buffer;

if (errno == EINTR) continue;
return std::error_code(errno, std::generic_category());
}
Buffer.set_size(Buffer.size() + ReadBytes);
} while (ReadBytes != 0);

}示例2: getMemoryBufferForStream
static error_code getMemoryBufferForStream(int FD,
StringRef BufferName,
std::unique_ptr<MemoryBuffer> &Result) {
const ssize_t ChunkSize = 4096*4;

}示例3: getSTDIN
error_code MemoryBuffer::getSTDIN(OwningPtr<MemoryBuffer> &result) {
// Read in all of the data from stdin, we cannot mmap stdin.
//
// FIXME: That isn't necessarily true, we should try to mmap stdin and
// fallback if it fails.

ssize_t ReadBytes;
// Read into Buffer until we hit EOF.
do {
