Function fromstr_skip_separator

numpy/core/src/multiarray/ctors.c:177–219

* Assuming that the separator is the next bit in the string (file), skip it. * * Single spaces in the separator are matched to arbitrary-long sequences * of whitespace in the input. If the separator consists only of spaces, * it matches one or more whitespace characters. * * If we can't match the separator, return -2. * If we hit the end of the string (file), return -1. * Otherwise, return

 * Otherwise, return 0.
