php_stream_copy_to_mem -- ストリームから確保されたバッファにデータをコピーする

説明

size_t php_stream_copy_to_mem ( php_stream * src, char ** buf, size_t maxlen, int persistent)

php_stream_copy_to_mem() allocates a buffer maxlen +1 bytes in length using pemalloc() (passing persistent ). It then reads maxlen bytes from src and stores them in the allocated buffer.

The allocated buffer is returned in buf , and the number of bytes successfully read. You, the caller, are responsible for freeing the buffer by passing it and persistent to pefree() .

If you want to copy all remaining data from the src stream, pass the constant PHP_STREAM_COPY_ALL as the value of maxlen .

注意 This function will attempt to copy the data in the most efficient manner, using memory mapped files when possible.
