Function NumPyOS_ascii_ftolf

numpy/core/src/common/numpyos.c:741–755

* NumPyOS_ascii_ftolf: * * fp: FILE pointer * * value: Place to store the value read * * Similar to PyOS_ascii_strtod, except that it reads input from a file. * * Similarly to fscanf, this function always consumes leading whitespace, * and any text that could be the leading part in valid input. * * Return value: similar to fscanf. * * 0 if no number read, * * 1 if a

 *      * EOF if end-of-file met before reading anything.
