This library contains memory buffer access functions for the MessagePack library cmp.
Usage (see example.c for a complete version):
cmp_mem_access_t mem;
cmp_ctx_t cmp;
char buffer[128];
// initialize memory access
cmp_mem_access_init(&cmp, &mem, buffer, sizeof(buffer));
// now you can use cmp to write to the buffer
cmp_write_int(&cmp, 42);
// reset to start of buffer
cmp_mem_access_set_pos(&mem, 0);
// read back from buffer
int32_t val;
cmp_read_int(&cmp, &val);The cmp_mem_access functions check buffer bounds and allow you to obtain the number of bytes written to the buffer using cmp_mem_access_get_pos(cmp_mem_access_t *)
Just include the two files
- cmp_mem_access.c
- cmp_mem_access.h
in your build
