ucommon  7.0.0
About: GNU uCommon C++ is a portable and optimized class framework for writing C++ applications that need to use threads and support concurrent synchronization, and that use sockets, XML parsing, object serialization, thread-optimized string and data structure classes, etc..

Function Documentation

◆ cpr_freep()

__EXPORT void cpr_freep ( void **  handle)

Definition at line 184 of file cpr.cpp.

Referenced by freep().

◆ cpr_memalloc()

__EXPORT void* cpr_memalloc ( size_t  size)

Portable memory allocation helper function. Handles out of heap error as a runtime error.

sizeof memory block to allocate from heap.
memory address of allocated heap space.

Definition at line 209 of file cpr.cpp.

◆ cpr_memassign()

__EXPORT void* cpr_memassign ( size_t  size,
caddr_t  address,
size_t  known 

Portable memory placement helper function. This is used to process "placement" new operators where a new object is constructed over a pre-allocated area of memory. This handles invalid values through runtime error.

sizeof object being constructed.
addresswhere the object is being placed.
knownsize of the location we are constructing the object in.

Definition at line 221 of file cpr.cpp.

◆ cpr_memswap()

__EXPORT void cpr_memswap ( void *  mem1,
void *  mem2,
size_t  size 

Portable swap code.

mem1to swap.
mem2to swap.
sizeof swap area.

Definition at line 193 of file cpr.cpp.

Referenced by ucommon::swap().

◆ cpr_newp()

__EXPORT void* cpr_newp ( void **  handle,
size_t  size 

Definition at line 175 of file cpr.cpp.

Referenced by newp().

◆ cpr_runtime_error()

__EXPORT void cpr_runtime_error ( const char *  text)

Function to handle runtime errors. When using the standard C library, runtime errors are handled by a simple abort. When using the stdc++ library with stdexcept, then std::runtime_error will be thrown.

textof runtime error.
