EOFW

Syntax EOFW (#ch)
Location SMS

This function is very similar to EOF in that it returns the value 0 if there is data waiting to be read from the specified channel, otherwise it returns 1. The difference is that this version of the function will however wait until data is received or the end of file code is received, which is especially useful on pipes which may not always work with EOF which returns 1 if the channel does not contain any data to be read.

CROSS-REFERENCE

See EOF. PEND and IO_PEND% are very similar.
