Purpose
Function to flush internal buffer
Syntax
FFLUSH(<expN>)
See Also
FCLOSE(), FLUSH, FOPEN(), FWRITE(), SET TBUFSIZE
Description
The FFLUSH() function works in conjunction with the FOPEN() and FWRITE() functions to flush the internal buffer. The <expN> is the file handle returned by the FOPEN() function. The FFLUSH() function is used to bypass the I/O buffer and commit open text files to the current device. The FCLOSE() function also flushes associated buffers as it closes the specified file.
Example
fwrite(fp,"Hello World") fflush(fp)
Products
Recital Server, Recital
