NAME

librock_ssfloat - string scan for a float, return characters processed
librock_ssdouble - string scan for a double, return characters processed

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/parse.h>

int
librock_ssfloat(const char *sptr,
                float *ret /* Conversion stored at *ret */
);

int
librock_ssdouble(const char *sptr,
                 double *ret /* Conversion stored at *ret */
);

DESCRIPTION

These functions are shallow wrappers around strtod(). Like the other librock_ss* functions, they return the number of characters processed, and store the result indirectly.

Typical use is step-by-step processing of text:

#ifdef librock_TYPICAL_USE_ssdouble
    double doubleVal;
    const char *ptr = " -20.30e-1";
    ptr += librock_ssdouble(ptr,&doubleVal);
    printf("%g\n",doubleVal);
#endif

USES

  strtod()
  malloc() free()   // #ifndef librock_FLATMEM
  librock_countbl() librock_counttowh()
  librock_strn0cpy()
