◆ pm_integer_free()

PRISM_EXPORTED_FUNCTION void pm_integer_free ( pm_integer_t * integer )

Free the internal memory of an integer.

This memory will only be allocated if the integer exceeds the size of a single node in the linked list.

Parameters

integer The integer to free.

Definition at line 666 of file pm_integer.c.

◆ pm_integer_string()

PRISM_EXPORTED_FUNCTION void pm_integer_string	(	pm_buffer_t *	buffer,
		const pm_integer_t *	integer
	)

Convert an integer to a decimal string.

Parameters

buffer	The buffer to append the string to.
integer	The integer to convert to a string.

Definition at line 607 of file pm_integer.c.

Field Documentation

◆ length

size_t pm_integer_t::length

The number of allocated values.

length is set to 0 if the integer fits into uint32_t.

Definition at line 25 of file pm_integer.h.

Referenced by pm_integer_compare(), pm_integer_string(), and pm_integers_reduce().

◆ negative

bool pm_integer_t::negative

Whether or not the integer is negative.

It is stored this way so that a zeroed pm_integer_t is always positive zero.

Definition at line 42 of file pm_integer.h.

Referenced by pm_integer_compare(), and pm_integer_string().

◆ value

uint32_t pm_integer_t::value

Embedded value for small integer.

This value is set to 0 if the value does not fit into uint32_t.

Definition at line 36 of file pm_integer.h.

Referenced by pm_integer_compare(), pm_integer_parse(), pm_integer_string(), and pm_integers_reduce().

◆ values

uint32_t* pm_integer_t::values

List of 32-bit integers.

Set to NULL if the integer fits into uint32_t.

Definition at line 30 of file pm_integer.h.

Referenced by pm_integer_compare(), pm_integer_free(), and pm_integer_string().
