DESCRIPTION
The strstr() function locates the first occurrence of the null-terminated string little in the null-terminated string big.
The strcasestr() function is similar to strstr(), but ignores the case of both strings.
The strcasestr_l() function does the same as strcasestr() but takes an explicit locale rather than using the current locale.
The strnstr() function locates the first occurrence of the null-terminated string little in the string big, where not more than len charac-
ters are searched. Characters that appear after a '
