Answer:
Here is the code:-
//include the required header files
#include<stdio.h>
#include<pthread.h>
// method protocol definition
void *count_lines(void *arg);
int main()
{
// Create a thread handler
pthread_t my_thread;
// Create a file handler
FILE *fh;
// declare the variable
int *linecnt;
// open the data file
fh=fopen("data.txt","r");
// Create a thread using pthread_create; pass fh to my_thread;
pthread_create(&my_thread, NULL, count_lines, (void*)fh);
//Use pthread_join to terminate the thread my_thread
pthread_join( my_thread, (void**)&linecnt );
// print the number of lines
printf("\nNumber of lines in the given file: %d \n\n", linecnt);
return (0);
}
// Method to count the number of lines
void *count_lines(void *arg)
{
// variable declaration and initialization
int linecnt=-1;
char TTline[1600];
//code to count the number of lines
while(!feof(arg))
{
fgets(TTline,1600,arg);
linecnt++;
}
pthread_exit((void *)linecnt);
// close the file handler
fclose(arg);
}
Explanation:
