SYNOPSIS
ssize_t
mongoc_stream_write (mongoc_stream_t *stream,
void *buf,
size_t count,
int32_t timeout_msec);
PARAMETERS
• stream: A mongoc_stream_t.
• buf: The buffer to write.
• count: The number of bytes to write.
• 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_write() function shall perform a write to a mongoc_stream_t. It's modeled on the API
and semantics of write(), though the parameters map only loosely.
WARNING:
The "default timeout" indicated by a negative value is both unspecified and unrelated to the
documented default values for *TimeoutMS URI options. To specify a default timeout value for a
*TimeoutMS URI option, use the MONGOC_DEFAULT_* constants defined in mongoc-client.h.
RETURNS
The mongoc_stream_write() function returns the number of bytes written on success. It returns -1 and sets
errno upon failure.
