NAME

SYNOPSIS

#include <librock/parse.h>
int
librock_ssconsl(
    const char *strptr,
    int radix,
    long librock_PTR *plRet
);

int
librock_sscons(
    const char *sptr,
    int radix,
    int *piRet
);

int
librock_ssdec(
    const char *sptr,
    int *piRet
);

DESCRIPTION

Skip leading ' ' or '\t', accept an optional '-', then convert to an int or long int in the specified radix (base.)

Stores conversion result indirectly (at pRet, if not NULL), and returns the number of characters processed.

Radix can be up to 36. A-Z are taken in upper or lower case for digits after 0-9.

When radix == 0, takes prefix from the string

     prefix - radix
       0    - octal
       0x   - hex
       0b   - binary
    default - decimal

Processing stops at the first character not a valid digit
in the radix.

Returns number of characters processed or 0 if could not
process any characters. If 0 is returned, the value at *pRet
is unchanged.

Typical use is to replace atol(), to gain the additional
radix conversions or to determine that characters were
processed.

• Source code which is Open-source, Free (Libre) and free (no cost)
• Namespace limited. All compile-time macros and names visible at link time are prefixed by "librock_". Integrate into your project and expect no name collisions.
• Stable API means new functions get new names so that there is no risk that updating a source file will break existing applications.
• Highly portable, cross-platform, and multithread compatible. Works with many machines, compilers, and operating systems (gcc/MSVC/Windows/Linux/BSD).
