int avio_get_str ( AVIOContext *  pb,
int  maxlen,
char *  buf,
int  buflen 
)

Read a string from pb into buf.

The reading will terminate when either a NULL character was encountered, maxlen bytes have been read, or nothing more can be read from pb. The result is guaranteed to be NULL-terminated, it will be truncated if buf is too small. Note that the string is not interpreted or validated in any way, it might get truncated in the middle of a sequence for multi-byte encodings.

Returns:
number of bytes read (is always <= maxlen). If reading ends on EOF or error, the return value will be one more than bytes actually read.

int avio_open ( AVIOContext **  s,
const char *  url,
int  flags 
)

Create and initialize a AVIOContext for accessing the resource indicated by url.

Note:
When the resource indicated by url has been opened in read+write mode, the AVIOContext can be used only for writing.
Parameters:
s Used to return the pointer to the created AVIOContext. In case of failure the pointed to value is set to NULL.
flags flags which control how the resource indicated by url is to be opened
Returns:
0 in case of success, a negative value corresponding to an AVERROR code in case of failure

Read a whole line of text from AVIOContext.

Stop reading after reaching either a

int ffio_rewind_with_probe_data ( AVIOContext *  s,
unsigned char *  buf,
int  buf_size 
)

Rewind the AVIOContext using the specified buffer containing the first buf_size bytes of the file.

Used after probing to avoid seeking. Joins buf and s->buffer, taking any overlap into consideration.

Note:
s->buffer must overlap with buf or they can't be joined and the function fails
Parameters:
s The read-only AVIOContext to rewind
buf The probe buffer containing the first buf_size bytes of the file
buf_size The size of buf
Returns:
0 in case of success, a negative value corresponding to an AVERROR code in case of failure
