Re: removing newline character from the buffer read by fgets

Is there any efficcient way of removing the newline character from the
buffer read by
fgets() ?

#include <stdio.h>
#include <string.h>

/* inside a function */
if (NULL != fgets(my_buffer, sizeof my_buffer, stdin)
{
char *nlptr = strchr(my_buffer, '\n');
if (nlptr) *nlptr = '\0';
}

Is there any library function that is similar to fgets() but also tells
how many
bytes it read into the buffer ?

You can certainly write one, a simple wrapper for fgets():

size_t my_fgets(char *buffer, size_t size, FILE *fp)
{
size_t result = 0;
if (NULL != fgets(my_buffer, sizeof my_buffer, fp)
{
/* optional, remove newline */
char *nlptr = strchr(my_buffer, '\n');
if (nlptr) *nlptr = '\0';
result = strlen(my_buffer);
}
return result;
}
