I understand your point, and thank you for the response. I think you missed my point, however, which is a method would be handy and less error prone. Case in point FLTK test code used atoi. Others might even use sscanf, and others may go out of their way and write a conversion from scratch. All overkill, if a method was provided.
just in case anyone is interested, following is a snippet on what the base value can be: If the value of base is 0, the expected form of the subject sequence is that of a decimal constant, octal constant or hexadecimal constant, any of which may be preceded by a + or - sign. A decimal constant begins with a non-zero digit, and consists of a sequence of decimal digits. An octal constant consists of the prefix 0 optionally followed by a sequence of the digits 0 to 7 only. A hexadecimal constant consists of the prefix 0x or 0X followed by a sequence of the decimal digits and letters a (or A) to f (or F) with values 10 to 15 respectively. http://opengroup.org/onlinepubs/007908775/xsh/strtol.html > > > (atio will not work for hex values) > > The atoi function is actually pretty brain-dead, so if you do not know > for certain that your numeric base is decimal, you should use strtol > instead, since it can be passed a base. > Also, if the given base is zero it makes a fairly convincing stab at > guessing the correct base. > I think the man pages actually say this, now I think of it... > > Attached example: > > #include <stdlib.h> > #include <stdio.h> > > int main(void) { > char *txt =3D "0x0000AA55"; > int v; > puts(txt); > > v =3D atoi(txt); > printf("v is : %d (atoi is explicitly base 10)\n", v); > > v =3D (int)strtol(txt, 0, 0); > printf("v is : %d or 0x%08X (strtol handles number base OK)\n", > v, v); > > return 0; > } > /* end of file */ > > > SELEX Galileo Ltd > Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS= > 14 3EL > A company registered in England & Wales.
