Function Documentation

void* 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 268 of file qgis.cpp.

void qgsFree

(

void *

ptr

)

Frees the memory space pointed to by ptr.

Works like C free().

Parameters

ptr	pointer to memory space

Definition at line 283 of file qgis.cpp.

void* 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

Definition at line 253 of file qgis.cpp.

bool qgsVariantGreaterThan	(	const QVariant &	lhs,
		const QVariant &	rhs
	)

Definition at line 315 of file qgis.cpp.
