- ID_INLINE mat3_t::mat3_t( float src[ 3 ][ 3 ] ) {
- memcpy( mat, src, sizeof( src ) );
- }
- The 'src' object is simply a pointer. Value 3x3 in the square brackets indicates to the programmer that he is working with an array of 3x3 items.
- But it is not an array of items which is passed into the function - it is only the pointer.
- So, the sizeof(src) expression will return value 4 or 8 (the size of the pointer in a 32-bit/64-bit system).
- This suspicious code was found in Wolf project by PVS-Studio static code analyzer.
- Warning message is:
- V511 The sizeof() operator returns size of the pointer, and not of the array, in 'sizeof (src)' expression. Splines math_matrix.h 94
