fmemcmp(3) Library Functions Manual fmemcmp(3) NAME fmemcmp - fuzzy comparison of two memory areas SYNOPSIS #include <fstrcmp.h> #define FSTRCMP_IDENTICAL #define FSTRCMP_THRESHOLD #define FSTRCMP_ERROR double fmemcmp(const void *data1, size_t size1, const void *data2, size_t size2); DESCRIPTION The fmemcmp() function compares the two memory areas, the size1 bytes pointed to by data1 and the size2 bytes pointed to by data2. RETURN VALUE The fmemcmp function returns a floating point value between 0.0 and FSTR- CMP_IDENTICAL. A value of 0.0 means the memory areas are utterly un-alike. A value of FSTRCMP_IDENTICAL means the memory areas are identical. A value of more than FSTRCMP_THRESHOLD (it lies between 0.0 and FSTRCMP_IDENTICAL) would be considered "similar" by most people. A value of FSTRCMP_ERROR (always negative) indicates a malloc(3) failure.
