fgets
Description:

Arguments:
Return Value:
Remarks:
Example:
Get a string from a stream
<stdio.h>
char *fgets(char *s, int n, FILE *stream);
s
n
stream
Returns a pointer to the string s if successful; otherwise, returns a null
pointer
The function reads characters from the input stream and stores them
into the string pointed to by s until it has read n-1 characters, stores a
newline character or sets the end-of-file or error indicators. If any char-
acters were stored, a null character is stored immediately after the last
read character in the next element of the array. If fgets sets the error
indicator, the array contents are indeterminate.
#include <stdio.h> /* for fgets, printf, */
#define MAX 50
int main(void)
{
}
Input:
Contents of afile.txt (used as input):
Short
Longer string
Output:
Short
|Longer string
|
FILE *buf;
char s[MAX];
if ((buf = fopen("afile.txt", "r")) == NULL)
else
{
}
printf("Cannot open afile.txt\n");
while (fgets(s, MAX, buf) != NULL)
{
}
fclose(buf);
printf("%s|", s);
