char * fgets ( char * str, int num, FILE * stream );
Get string from stream
Reads characters from stream and stores them as a C string into str until (num-1) characters have been read or either a newline or a the End-of-File is reached, whichever comes first.
A newline character makes fgets stop reading, but it is considered a valid character and therefore it is included in the string copied to str.
A null character is automatically appended in str after the characters read to signal the end of the C string.
Parameters
str
Pointer to an array of chars where the string read is stored.
num
Maximum number of characters to be read (including the final null-character). Usually, the length of the array passed as str is used.
stream
Pointer to a FILE object that identifies the stream where characters are read from.
To read from the standard input, stdin can be used for this parameter.
/* fgets example */
#include <stdio.h>
int main()
{
FILE * pFile;
char mystring [100];
pFile = fopen ("myfile.txt" , "r");
if (pFile == NULL) perror ("Error opening file");
else {
if ( fgets (mystring , 100 , pFile) != NULL )
puts (mystring);
fclose (pFile);
}
return 0;
