Function Documentation

unsigned int dtoi (  const char *  string  )

Convert a decimal string into an unsigned integer. Parameters: string  Decimal string to convert Returns: integer value of the string

unsigned long long dtoll (  const char *  string  )

Convert a decimal string into an unsigned long long. Parameters: string  Decimal string to convert Returns: long long value of the string

unsigned int ischar (  const char *  string  )

Test a string to see if it is a valid register wide character element. Parameters: string  Layer address string to convert Return values: 1  if the string has valid characters before the start of the next tag 0  if the string does not have valid characters before the start of the next tag Checks that the string has valid characters after any leading whitespace and before the start of the next tag.

unsigned int isdec (  const char *  string  )

Test a string to see if it is a hexadecimal number. Parameters: string  Hex string to convert Return values: 1  if the string is a valid dec string 0  if the string is not a valid dec string Test is quite weak, checks that the string starts with zero or more whitespace characters followed by "one or more numerical characters ('0' to '9').

unsigned int ishex (  const char *  string  )

Test a string to see if it is a hexadecimal number. Parameters: string  Hex string to convert Return values: 1  if the string is a valid hex string 0  if the string is not a valid hex string Test is quite weak, checks that the string starts with zero or more whitespace characters followed by "0x" followed by one or more hex characters ('0' to '9', 'a' to 'f' and 'A' to 'f').

unsigned XLX_getAttribute (  const char **  attribute, const char *  name, int *  value )

Find name in the attribute list and sets value accordingly. Parameters: attribute  Attribute list from the start tag of the element name  Attribute to find and return value  Location to put value of attribute Return values: 0  If the name is found in the attribute list -1  If the name is missing from the attribute list

unsigned XLX_isEnabled (  const char **  attribute, int *  enabled )

Reads the attribute list and sets enabled accordingly. Parameters: attribute  Attribute list from the start tag of the element enabled  Location to write 0 (FALSE) or 1 (TRUE) Return values: 0  If the attribute list was read correctly -1  If there was a bad attribute

unsigned XLX_pow (  unsigned  exp  )

calculates 16 to the power x Parameters: exp  Exponent Returns: 16 raised to the power exp

unsigned int xtoi (  const char *  string  )

Convert a hexedecimal string into an unsigned integer. Parameters: string  Hex string to convert Returns: integer value of the string

unsigned long long xtoll (  const char *  string  )

Convert a hexedecimal string into an unsigned long long. Parameters: string  Hex string to convert Returns: long long value of the string
