## Detailed Description

The charstring class provides static methods for manipulating C-style character strings.

In addition to some unique methods, analogs for the standard C string functions are provided. However, unlike the standard C string functions, the charstring methods are NULL safe. Your application will not crash if a NULL is passed in, and instead, will give intuitive results.

|  | char *** | list,
|  | uint64_t * | listlength
| ) |  |

static

Parses "string" of character length "stringlength" delimited by NULL-terminated "delimiter" and allocates "listlength" elements of "list" to return the parts. If "collapse" is true then multiple instances of the delimiter in a row will be interpreted as one instance of the delimiter. Each member of "list" and "list" itseslf must be deallocated by the calling program.

## split() [4/4]

static

Parses "string" of character length "stringlength" delimited by "delimiter" of character length "delimiterlength" and allocates "listlength" elements of "list" to return the parts. If "collapse" is true then multiple instances of the delimiter in a row will be interpreted as one instance of the delimiter. Each member of "list" and "list" itseslf must be deallocated by the calling program.

## startsWith()

static bool charstring::startsWith | ( | const char * | haystack,
|  | const char * | needle
| ) |  |

static

Returns true if "haystack" starts with "needle" or false otherwise.

## strip() [1/2]

static bool charstring::strip | ( | char * | str,
|  | char | character
| ) |  |

static

Strips all instances of "character" from "str". Returns true if any characters were stripped and false if no characters were stripped.

## strip() [2/2]

static bool charstring::strip | ( | char * | str1,
|  | const char * | str2
| ) |  |

static

Strips all instances of "str2" from "str1". Returns true if any characters were stripped and false if no characters were stripped.

## stripSet()

static bool charstring::stripSet | ( | char * | str1,
|  | const char * | set
| ) |  |

static

Strips all instances of any character in "set" from "str1". Returns true if any characters were stripped and false if no characters were stripped.

## subString() [1/2]

static char* charstring::subString | ( | const char * | str,
|  | size_t | start
| ) |  |

static

Returns a copy of the segment of "str" between string index "start" and the end of the string, inclusive.

## subString() [2/2]

static char* charstring::subString | ( | const char * | str,
|  | size_t | start,
|  | size_t | end
| ) |  |

static

Returns a copy of the segment of "str" between string indices "start" and "end", inclusive.

## toFloat() [1/2]

static long double charstring::toFloat | ( | const char * | string | ) |

static

Converts "string" to a floating point number.

## toFloat() [2/2]

static long double charstring::toFloat | ( | const char * | string,
|  | const char ** | endptr
| ) |  |

static

Converts "string" to a floating point number. If non-NULL, endptr will be set to the first character in the string after the number.

## toFloatC()

static long double charstring::toFloatC | ( | const char * | string | ) |

static

Converts "string" to a floating point number.

If "string" uses a "." as a decimal point (per the "C" locale) then the "." is first converted to the appropriate decimal-delimiter for the current locale.

(Currently only supported on linux/unix platforms that provide the locale.h header. On other platforms, it just falls through to toFloat().)

## toInteger() [1/4]

static int64_t charstring::toInteger | ( | const char * | string | ) |

static

Converts "string" to a 64-bit integer.

## toInteger() [2/4]

static int64_t charstring::toInteger | ( | const char * | string,
|  | const char ** | endptr
| ) |  |

static

Converts "string" to a 64-bit integer. If non-NULL, endptr will be set to the first character in the string after the number.

## toInteger() [3/4]

static int64_t charstring::toInteger | ( | const char * | string,
|  | const char ** | endptr,
|  | int32_t | base
| ) |  |

static

Converts "string" to a 64-bit integer of base "base". If non-NULL, endptr will be set to the first character in the string after the number.

## toInteger() [4/4]

static int64_t charstring::toInteger | ( | const char * | string,
|  | int32_t | base
| ) |  |

static

Converts "string" to a 64-bit integer of base "base".

## toUnsignedInteger() [1/4]

static uint64_t charstring::toUnsignedInteger | ( | const char * | string | ) |

static

Converts "string" to a 64-bit unsigned integer.

## toUnsignedInteger() [2/4]

static uint64_t charstring::toUnsignedInteger | ( | const char * | string,
|  | const char ** | endptr
| ) |  |

static

Converts "string" to a 64-bit unsigned integer. If non-NULL, endptr will be set to the first character in the string after the number.

## toUnsignedInteger() [3/4]

static uint64_t charstring::toUnsignedInteger | ( | const char * | string,
|  | const char ** | endptr,
|  | int32_t | base
| ) |  |

static

Converts "string" to a 64-bit unsigned integer of base "base". If non-NULL, endptr will be set to the first character in the string after the number.

## toUnsignedInteger() [4/4]

static uint64_t charstring::toUnsignedInteger | ( | const char * | string,
|  | int32_t | base
| ) |  |

static

Converts "string" to a 64-bit unsigned integer of base "base".

## unescape() [1/2]

static char* charstring::unescape | ( | const char * | input | ) |

static

unescapes all -escaped characters found in "input" and returns the result in a buffer allocated inside the function. This buffer must be deleted by the calling program.

## unescape() [2/2]

static void charstring::unescape | ( | const char * | input,
|  | uint64_t | inputlength,
|  | char ** | output,
|  | uint64_t * | outputlength
| ) |  |

static

similar to unescape() above, but takes an "inputlength" parameter and returns the result in "output" and "outputlength" rather than in a return value

## upper()

static void charstring::upper | ( | char * | str | ) |

static

Converts "str" to uppercase.

## zero()

static void charstring::zero | ( | char * | str,
|  | size_t | len
