We don't need to use strlen(), a var, or check for the end explicitely,
isspace('\0') is false:
[acme@jouet c]$ cat ltrim.c
#include <ctype.h>
#include <stdio.h>
static char *ltrim(char *s)
{
while (isspace(*s))
++s;
return s;
}
int main(void)
{
printf("ltrim(\"\")='%s'\n", ltrim(""));
return 0;
}
[acme@jouet c]$ ./ltrim
ltrim("")=''
[acme@jouet c]$
