bs_capacityassert(3) Library Functions Manual bs_capacityassert(3) NAME bs_capacityassert - assert that there are least n bytes left in the stream SYNTAX #include <libowfat/parse.h> int bs_capacityassert(struct bytestream* &bs, size_t capacity); DESCRIPTION bs_capacityassert will check that there are at least this many bytes in the bytestream. If there are not, it will set the bytestream to the er- ror state and return 0; otherwise it will return 1. Note that this compares against the limits of the bytestream, not the actual length. These are often the same, but bytestreams can be tied to a buffer*, in which case the actual length of the stream is not known beforehand. Even if bs_capacityassert returns successful, the following actual reads could still run into an error. bs_capacitycheck does the same thing but does not set the bytestream to the error state if there is not enough space. Us bs_capacityleft to find out how many bytes are left in the bytestream. bs_nomoredataassert is the inverse assertion. Use bs_err to find out whether the bytestream is in the error state.
