typedef unsigned long long qgssize

qgssize is used instead of size_t, because size_t is stdlib type, unknown by SIP, and it would be hard to define size_t correctly in SIP.

Currently used "unsigned long long" was introduced in C++11 (2011) but it was supported already before C++11 on common platforms. "unsigned long long int" gives syntax error in SIP. KEEP IN SYNC WITH qgssize defined in SIP!

Function Documentation

void CORE_EXPORT* qgsCalloc	(	size_t	nmemb,
		size_t	size
	)

Allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory.

Works like C calloc() but prints debug message by QgsLogger if allocation fails.

Parameters

nmemb	number of elements
size	size of element in bytes

Definition at line 202 of file qgis.cpp.

bool qgsDoubleNear	(	double	a,
		double	b,
		double	epsilon = `4 * DBL_EPSILON`
	)

inline

Definition at line 327 of file qgis.h.

bool qgsDoubleNearSig	(	double	a,
		double	b,
		int	significantDigits = `10`
	)

inline

Definition at line 336 of file qgis.h.

QString qgsDoubleToString	(	const double &	a,
		const int &	precision = `17`
	)

inline

Definition at line 319 of file qgis.h.

void CORE_EXPORT qgsFree ( void * ptr )

Frees the memory space pointed to by ptr.

Works like C free().

Parameters

ptr	pointer to memory space

Definition at line 217 of file qgis.cpp.

void CORE_EXPORT* qgsMalloc ( size_t size )

Allocates size bytes and returns a pointer to the allocated memory.

Works like C malloc() but prints debug message by QgsLogger if allocation fails.

Parameters

size	size in bytes
