NAME¶
fmemcmp - fuzzy comparison of two memory areasSYNOPSIS¶
#include <fstrcmp.h>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 FSTRCMP_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.SEE ALSO¶
