Member Function Documentation

atoi64()

static int64_t TSLPlatformHelper::atoi64 ( const char * number )

static

This method converts a string to a 64bit integer.

Calls either the _atoi64 on windows or C99 atoll. See system manual pages for specific limitations.

The current locale is used.

Parameters

number

string to be converted

Returns

the converted number.

isnan()

static bool TSLPlatformHelper::isnan ( double dsrc )

static

This method checks to see if a double is a NAN.

Returns true if the double is not a number, false otherwise.

Argument:

dsrc : a double-precision floating point value.

strcasestr()

static const char * TSLPlatformHelper::strcasestr ( const char * str1, const char * str2 )

static

Searches str1 for occurrences of str2, ignoring case sensitivity.

Returns a pointer to the first occurrence of str2, or null if not present.

Parameters

str1	The string to search
str2	The string to search for.

stricmp()

static int TSLPlatformHelper::stricmp ( const char * str1, const char * str2 )

static

Case-insensitive string comparison.

The current system locale is used.

Parameters

str1	Null terminated string.
str2	Null terminated string.

Returns

integer value corresponding to:

• < 0 str1 is less that str2
• 0 str1 is identical to str2
• > 0 str1 is greater than str2

strnicmp()

static int TSLPlatformHelper::strnicmp ( const char * str1, const char * str2, size_t n )

static

Case-insensitive string comparison of first n characters.

The current system locale is used.

Parameters

str1	Null terminated string.
str2	Null terminated string.
n	the number of characters to compare.

Returns

integer value corresponding to:

• < 0 str1 substring is less that str2 substring
• 0 str1 substring is identical to str2 substring
• > 0 str1 substring is greater than str2 substring
