)
Description
Arguments
Return Value
Error Codes
Notes
The malloc() function allocates memory for an object whose size is specified by
size and whose value is indeterminate. malloc() calls the pSOS+ region manager
to allocate the memory. The caller can be blocked if memory is not available and the
wait option is selected in the pREPC+ Configuration Table. Memory is allocated from
Region 0.
size Specifies the number of bytes to allocate.
This function returns either a pointer to the allocated memory or a null pointer if no
memory is allocated. If an error occurs, errno is set.
