Emulator of C language fprintf function. This function is obsolete
fprintf(file,format,value_1,..,value_n)
:
This function is obsolete, use preferabily the mfprintf function which is much more compatible with the C fprintf functionalities.
The fprintf function converts, formats, and writes its value parameters, under control of the format parameter, to the file specified by its file parameter.
The format parameter is a character string that contains two types of objects:
:Literal characters which are copied to the output stream. : :Conversion specifications each of which causes zero or more items
to be fetched from the value parameter list. See printf_conversion for details.
:
If any value`s remain after the entire `format has been processed, they are ignored.
u=`file`_('open',`fullfile`_(TMPDIR,'results'),'unknown') //open the result file
t=0:0.1:2*%pi;
for tk=t
fprintf(u,'time = %6.3f value = %6.3f',tk,`sin`_(tk)) // write a line
end
`file`_('close',u) //close the result file
fprintf(0,'My error which is going to be displayed on the stderr')
