termkey_push_bytes - supply more bytes to the input buffer

  #include <termkey.h>

  size_t termkey_push_bytes(TermKey *tk, const char *bytes, size_t len");

Link with -ltermkey.

termkey_push_bytes*() allows more bytes of input to be supplied directly into the input buffer of the *termkey*(7) instance. If there was no buffer space remaining then -1 is returned with errno set to *ENOMEM.

This function, along with termkey_getkey*(3), makes it possible to use the *termkey instance with a source of bytes other than from reading a filehandle.

For synchronous usage, *termkey_waitkey*(3) performs the input blocking task. For use against a regular stream filehandle that supports *read*(2), see *termkey_advisereadable*(3).

termkey_push_bytes*() the number of bytes consumed from the input (which may be smaller than the length provided, if the buffer runs out of space) or -1 cast to *size_t if an error occurs, in which case errno is set accordingly.
