fprintf

Emulator of C language fprintf function. This function is obsolete.

Calling Sequence

fprintf(file, format, value_1, ..., value_n)

Arguments

format

a Scilab string. It specifies a character string combining literal characters with conversion specifications.

value_i

specifies the data to be converted according to the format parameter.

file

a Scilab string specifying a file name or a logical unit number (see file)

Note that if file=0, the message will be display on standard error stream (stderr).

Description

This function is obsolete, use preferabily the mfprintf function which is much more compatible with the C fprintf functionalities.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 values remain after the entire format has been processed, they are ignored.

Examples

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')
