If negative, use the default timeout. .UNINDENT .sp The \fBmongoc_stream_read()\fP function shall perform a read from a \fBmongoc_stream_t\fP\&. It\(aqs modeled on the API and semantics of \fBread()\fP, though the parameters map only loosely. .SH RETURNS .sp The \fBmongoc_stream_read\fP function returns the number of bytes read on success. It returns \fB>= 0\fP and \fB< min_bytes\fP when end\-of\-file is encountered and \fB\-1\fP on failure. \fBerrno\fP is set upon failure. .SH SEE ALSO .sp \fBmongoc_stream_readv()\fP .sp \fBmongoc_stream_write()\fP .sp \fBmongoc_stream_writev()\fP .SH AUTHOR MongoDB, Inc .SH COPYRIGHT 2017-present, MongoDB, Inc .\" Generated by docutils manpage writer. .
