If there is an error, NULL is returned and \fBerror\fP is filled out; if there is no error but no matching file is found, NULL is returned and the error code and domain are 0. .sp This function is considered a retryable read operation. Upon a transient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If \fBretryreads\fP is false in the URI (see \fI\%mongoc_uri_t\fP) the retry behavior does not apply. .SH ERRORS .sp Errors are propagated via the \fBerror\fP parameter. .SH RETURNS .sp Returns a newly allocated \fI\%mongoc_gridfs_file_t\fP if successful. You must free the resulting file with \fI\%mongoc_gridfs_file_destroy()\fP when no longer in use. .SH AUTHOR MongoDB, Inc .SH COPYRIGHT 2017-present, MongoDB, Inc .\" Generated by docutils manpage writer. .
