_leb128_unsigned_encode64: _leb128_signed_encode64:
_leb128_unsigned_encode32: _leb128_signed_encode32: - encode leb128
integers
SYNOPSIS
#include <cmplrs/leb128.h>
int _leb128_unsigned_encode64(__uint64_t number, char* buffer);
int _leb128_signed_encode64(__int64_t number, char* buffer);
int _leb128_unsigned_encode32(__uint32_t number, char* buffer);
int _leb128_signed_encode32(__int32_t number, char* buffer);
DESCRIPTION
These routines encode integers into the leb128 format. The leb128 format
is a variable-length encoding extensively used in the DWARF debugging
information format and is described in the DWARF documentation.
The encoded number is placed into buffer and the number of bytes of
buffer used to encode the number is returned.
Link with the option -lelfutil to link in these routines.
The arguments are as follows:
number
is the input number to be converted to leb128 format.
buffer is a buffer provided by the caller. The pointed-at-buffer must
be at least 5 bytes long for the 64-bit input integers and at
least 10 bytes long for the 32 bit input integers. No buffer
overrun checking is possible in these routines so the caller must
provide the required buffer space.

DIAGNOSTICS
Returns the number of bytes used to encode the number. The returned
value will be in the range 1 to 5 for the 32-bit number input versions.
The returned value will be in the range 1 to 10 for the 64-bit number
input versions.
