Function Documentation

void explain_buffer_errno_malloc ( explain_string_buffer_t sb,
int  errnum,
size_t  size 
)

The explain_buffer_errno_malloc function is used to obtain an explanation of an error returned by the malloc(3) system call. The least the message will contain is the value of strerror(errnum), but usually it will do much better, and indicate the underlying cause in more detail.

Parameters:
sbThe string buffer to print the message into. If a safe buffer is specified, this function is thread safe.
errnumThe error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.
sizeThe original size, exactly as passed to the malloc(3) system call.

void explain_buffer_errno_malloc_explanation ( explain_string_buffer_t sb,
int  errnum,
const char *  syscall_name,
size_t  size 
)

The explain_buffer_errno_malloc_explanation function is used to obtain an explanation of an error returned by the malloc(3) system call, the part after "because".

Parameters:
sbThe string buffer to print the message into.
errnumThe error value to be decoded.
syscall_nameThe name of the offending system call.
sizeThe original size, exactly as passed to the malloc(3) system call.
