Function Documentation

float explain_strtof_on_error ( const char *  nptr,
char **  endptr 
)

The explain_strtof_on_error function is used to call the strtof(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtof(3) function.

Parameters:
nptrThe nptr, exactly as to be passed to the strtof(3) system call.
endptrThe endptr, exactly as to be passed to the strtof(3) system call.
Returns:
The value returned by the wrapped strtof(3) system call.
Example:
This function is intended to be used in a fashion similar to the following example:
 float result = explain_strtof_on_error(nptr, endptr);
 if (result < 0)
 {
     ...cope with error
     ...no need to print error message
 }
