case_lowers converts each uppercase byte in the string s to lowercase. s must be 0-terminated. case_lowerb converts each uppercase byte in the buffer s , of length len , to lowercase. case_diffs lexicographically compares lowercase versions of the strings s and t . It returns something positive, negative, or zero when the first is larger than, smaller than, or equal to the second. s and t must be 0-terminated. case_equals means !case_diffs . case_starts returns 1 if a lowercase version of s starts with a lowercase version of t . s and t must be 0-terminated. case_diffb lexicographically compares lowercase versions of the buffers s and t , each of length len . It returns something positive, negative, or zero when the first is larger than, smaller than, or equal to the second. case_startb returns 1 if a lowercase version of the buffer s , of length len , starts with a lowercase version of the string t . t must be 0-terminated. The case routines are ASCII-specific. They are suitable for programs that handle case-independent networking protocols. All comparisons are performed on unsigned bytes. byte_diff(3), byte_equal(3), str_diff(3), str_equal(3), str_start(3)
