Description

str_chr returns the index of the first occurrance of needle or \0 in string.

str_copy copies the leading bytes of in to out up to and including the first occurrance of \0. str_copy returns the number of bytes copied.

str_rchr returns the index of the last occurrance of needle or the first occurrance of \0 in string.

str_diff returns negative, 0, or positive, depending on whether the string a[0], a[1], ..., a[n]=='\0' is lexicographically smaller than, equal to, or greater than the string b[0], b[1], ..., b[m-1]=='\0'. If the strings are different, str_diff does not read bytes past the first difference.

str_diffn returns negative, 0, or positive, depending on whether the string a[0], a[1], ..., a[n]=='\0' is lexicographically smaller than, equal to, or greater than the string b[0], b[1], ..., b[m-1]=='\0'. If the strings are different, str_diff does not read bytes past the first difference. The strings will be considered equal if the first limit characters match.

str_equal returns nonzero if a and b match up to and including the first occurrance of \0. If the strings are different, str_equal does not read bytes past the first difference.

str_len returns the index of the first occurrance of \0 in string.

str_start returns 1 if b is a prefix of a, 0 otherwise.
