Library of Functions for Tasks
fgets
Task function category: Functions Operating on Files
Returns the next characters from the file represented by the file variable FILE, or EOF if the end
of the file has been reached. It has the same behavior as the C fgets function: the function stops
reading when NB_CHARS characters have been read or if a \n character is read (in which case,
\n is the last character of the returned string).
Usage
fgets(FILE, NB_CHARS)
Arguments
• FILE
File variable.
• NB_CHARS
Number of characters.
Examples
Example 1:
.define_task read_file
set myfile = NULL
set s = ""
myfile = fopen ("./hello.txt", "r")
while(1)
s = fgets(myfile, 200)
if (s == EOF)
break
else
printf(stdout, "%s", s)
endif
endwhile
fclose (myfile)
.end_define_task
Example 2:
900
