## Description

GstByteReader provides a byte reader that can read different integer and floating point types from a memory buffer. It provides functions for reading signed/unsigned, little/big endian integers of 8, 16, 24, 32 and 64 bits and functions for reading little/big endian floating points numbers of 32 and 64 bits. It also provides functions to read NUL-terminated strings in various character encodings.

## Details

### GstByteReader

    typedef struct {

Scan for pattern `pattern` with applied mask `mask` in the byte reader data, starting from offset `offset` relative to the current position.

The bytes in `pattern` and `mask` are interpreted left-to-right, regardless of endianness. All four bytes of the pattern must be present in the byte reader data for it to match, even if the first or last bytes are masked out.

It is an error to call this function without making sure that there is enough data (offset+size bytes) in the byte reader.

`reader` : | a GstByteReader
`mask` : | mask to apply to data before matching against `pattern`
`pattern` : | pattern to match (after mask is applied)
`offset` : | offset from which to start scanning, relative to the current position
`size` : | number of bytes to scan from offset

Returns :

offset of the first match, or -1 if no match was found. Example:

    // Assume the reader contains 0x00 0x01 0x02 ... 0xfe 0xff
    gst_byte_reader_masked_scan_uint32 (reader, 0xffffffff, 0x00010203, 0, 256);
    // -> returns 0

    // -> returns -1
    gst_byte_reader_masked_scan_uint32 (reader, 0xffffffff, 0x01020304, 1, 255);
    // -> returns 1
    gst_byte_reader_masked_scan_uint32 (reader, 0xffff, 0x0001, 0, 256);
    // -> returns -1
    gst_byte_reader_masked_scan_uint32 (reader, 0xffff, 0x0203, 0, 256);
    // -> returns 0
