void *	spGetSymbolAddress (void *handle, const char *symbol)
void	spCloseLibrary (void *handle)

Detailed Description

Function Documentation

spOpenLibrary()

void * spOpenLibrary ( const char * filename )

extern

Opens the dynamic library associated with filename. The behavior of multiple function calls for the same library depends on an environment. On some environments the function calls map the library to multiple address spaces, on others the calls map the library to one address space. Therefore, you have to write code independent from this behavior. Moreover, the behavior without directory path depends on an environment.

Parameters

[in]

filename

The null-terminated name of the file associated with the dynamic library.

Returns

The handle of the library.

extern

Parameters

[in]	handle	The handle of the dynamic library.
[in]	symbol	The null-terminated name of the function. For example, symbol is "func" if the function is func.

Returns

The address of the function. This address can be used as the pointer to the function.
