NAMEmongoc_stream_read − mongoc_stream_read()

---

SYNOPSIS ssize_t mongoc_stream_read (mongoc_stream_t *stream, void *buf, size_t count, size_t min_bytes, int32_t timeout_msec);

---

PARAMETERS • stream: A mongoc_stream_t​. • buf: The buffer to read into. • count: The number of bytes to read. • min_bytes: The minimum number of bytes to read, or else indicate failure. • timeout_msec: The number of milliseconds to wait before failure, a timeout of 0 will not block. If negative, use the default timeout. The mongoc_stream_read() function shall perform a read from a mongoc_stream_t​. It's modeled on the API and semantics of read(), though the parameters map only loosely.

---

RETURNSThe mongoc_stream_read function returns the number of bytes read on success. It returns >= 0 and < min_bytes when end−of−file is encountered and −1 on failure. errno is set upon failure.
