For example, rather than: - - pairing_init_inp_str(pairing, stdin); - -write something like: - - char s[1024]; - size_t count = fread(s, 1, 1024, stdin); - if (!count) pbc_die("input error"); - if (pairing_init_set_buf(pairing, s, count)) pbc_die("pairing init failed"); - -For file reads, personally I like to use mmap() which suits -pairing_init_set_buf(). - -The `pbc_param_t` data type for pairing parameters replaces `a_param_t`, ..., -`g_param_t`. Having the same data type for all pairing parameter types -simplifies the library, though some functions had to be changed slightly. - -At last, one can initialize a `pairing_t` from a `pbc_param_t`: - - pairing_t p; - pbc_param_t par; - pbc_param_init_a_gen(par, 160, 512); - pairing_init_pbc_param(p, par); - pbc_param_clear(par); - -=== Minor differences === - -I trimmed the API. The file stream operations are gone. I removed the -fetch_ops_t and tracker_t types: the standard C library already provides -routines for reading from disk to memory. - -I refactored to avoid exposing `symtab_t` and `darray_t`, and undocumented -routines such as `poly_alloc()`. I mostly preserved the headers that define -these functions, but they are no longer included by `pbc.h`. - -I replaced the CMake files with `simple.make`, which I use during development, -though I test the autotools build before release. - -To reduce symbol pollution, all official functions and variables of the PBC -now start with `pbc_`, `field_`, `element_` or `pairing_`. Other names mostly -have hidden visibility in a shared library. Watch out for renamed functions. |
