13 int fmemcmpi(const void *data1, size_t size1, const void *data2, size_t
14 size2);

17 The fmemcmpi() function compares the two memory areas, the size1 bytes
18 pointed to by data1 and the size2 bytes pointed to by data2.
19
21 The fmemcmpi function returns an int value between 0 and FSTRCMPI_IDEN‐
22 TICAL. A value of 0 means the memory areas are utterly un‐alike. A
23 value of FSTRCMPI_IDENTICAL means the memory areas are identical. A
24 value of more than FSTRCMPI_THRESHOLD (it lies between 0.0 and FSTR‐
25 CMP_IDENTICAL) would be considered "similar" by most people.
26
27 A value of FSTRCMPI_ERROR (always negative) indicates a malloc(3) fail‐
28 ure.

45 The comparison code is derived from the fuzzy comparison functions in
46 GNU Gettext 0.17. The GNU Gettext comparison functions were, in turn,
47 derived from GNU Diff 2.7.
