## Detailed Description

Definition in file muldiv.h.

## ◆ round_to_next_multiple_of()

 unsigned round_to_next_multiple_of ( unsigned number, unsigned divisor )

Return the lowest x such that x is at least number, and x modulo divisor == 0. If no such x can be expressed as an unsigned, return UINT_MAX. Asserts if divisor is zero.

Definition at line 21 of file muldiv.c.

## ◆ round_uint32_to_next_multiple_of()

 uint32_t round_uint32_to_next_multiple_of ( uint32_t number, uint32_t divisor )

Return the lowest x such that x is at least number, and x modulo divisor == 0. If no such x can be expressed as a uint32_t, return UINT32_MAX. Asserts if divisor is zero.

## ◆ round_uint64_to_next_multiple_of()

 uint64_t round_uint64_to_next_multiple_of ( uint64_t number, uint64_t divisor )

Return the lowest x such that x is at least number, and x modulo divisor == 0. If no such x can be expressed as a uint64_t, return UINT64_MAX. Asserts if divisor is zero.
