NAME

mtbl_fixed - Fixed-width encoding and decoding of 32 and 64 bit integers

SYNOPSIS

#include <mtbl.h>

size_t mtbl_fixed_encode32(uint8_t * dst , uint32_t value );

size_t mtbl_fixed_encode64(uint8_t * dst , uint64_t value );

uint32_t mtbl_fixed_decode32(const uint8_t * ptr );

uint64_t mtbl_fixed_decode64(const uint8_t * ptr );

DESCRIPTION

mtbl_fixed_encode32 () and mtbl_fixed_encode64 () write the 32 or 64 bit quantity, respectively, in the argument value to the buffer in the argument dst . The quantity will be written in little endian order, regardless of host architecture.

mtbl_fixed_decode32 () and mtbl_fixed_decode64 () read and return the 32 or 64 bit quantity, respectively, in the argument ptr . The quantity will be read in little endian order, regardless of host architecture.

Bounds checking must be performed by the caller.

RETURN VALUE

mtbl_fixed_encode32 () and mtbl_fixed_encode64 () return the number of bytes written to the buffer. (4 or 8, respectively.)

mtbl_fixed_decode32 () and mtbl_fixed_decode64 () return the decoded quantity.
