_fmpq_poly_set_str

Synopsis#include <flint/fmpq_poly.h>
int _fmpq_poly_set_str(fmpz * poly, fmpz_t den, const char * str, slong len)source

Sets (poly, den) to the polynomial specified by the null-terminated string str of len coefficients. The input format is a sequence of coefficients separated by one space.

The result is only guaranteed to be in lowest terms if all coefficients in the input string are in lowest terms.

Returns 0 if no error occurred. Otherwise, returns -1 in which case the resulting value of (poly, den) is undefined. If str is not null-terminated, calling this method might result in a segmentation fault.
