NAME
mongoc_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.
RETURNS
The 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. SEE ALSO: mongoc_stream_readv() mongoc_stream_write() mongoc_stream_writev()
