Once a file has been opened for writing a string can be written to the
file using the fputs
function. The following example shows
how to write the string ‘Free Software is needed for Free Science’
to the file ‘free.txt’.
filename = "free.txt"; fid = fopen (filename, "w"); fputs (fid, "Free Software is needed for Free Science"); fclose (fid);
Write the string string to the file with file descriptor fid.
The string is written to the file with no additional formatting. Use
fdisp
instead to automatically append a newline character appropriate
for the local machine.
Return a non-negative number on success or EOF on error.
A function much similar to fputs
is available for writing data
to the screen. The puts
function works just like fputs
except it doesn’t take a file pointer as its input.
Write a string to the standard output with no formatting.
The string is written verbatim to the standard output. Use disp
to
automatically append a newline character appropriate for the local machine.
Return a non-negative number on success and EOF on error.
