2.3 Byte Streams¶
-
typedef int (*SerdStreamErrorFunc)(void *stream)¶
Function to detect I/O stream errors.
Identical semantics to
ferror
.- Returns:
Non-zero if
stream
has encountered an error.
-
typedef size_t (*SerdSource)(void *buf, size_t size, size_t nmemb, void *stream)¶
Source function for raw string input.
Identical semantics to
fread
, but may set errno for more informative error reporting than supported by SerdStreamErrorFunc.- Param buf:
Output buffer.
- Param size:
Size of a single element of data in bytes (always 1).
- Param nmemb:
Number of elements to read.
- Param stream:
Stream to read from (FILE* for fread).
- Returns:
Number of elements (bytes) read.
-
typedef size_t (*SerdSink)(const void *buf, size_t len, void *stream)¶
Sink function for raw string output.
