* Fix errors detected by the GCC compiler (pointer conversions and format mismatches). * Worked around a GCC flow analysis issue in base64.c where the compiler is convinced that there is a path through the code where "input" is used but not initialized. * Added EFIAPI to the file system operation routines for sockets to match the API declaration. Note for GCC, the meaning of "l" and "L" are different in printf and sscanf format strings. The lower case "l" indicates a 32-bit value where the capital "L" indicates a 64-bit value. The native (default) integer size may be represented by a size letter of "n".

Read support routine for sockets
|
|
|
|
The BslSocketRead routine is called indirectly by the read file
|
|
system routine. This routine is typically used for SOCK_STREAM
|
|
because it waits for receive data from the target system specified
|
|
in the ::connect call.
|
|
|
|
@param [in] pDescriptor Descriptor address for the file
|
|
@param [in] pOffset File offset
|
|
@param [in] LengthInBytes Number of bytes to read
|
|
@param [in] pBuffer Address of the buffer to receive the data
|
|
|
|
@return The number of bytes read or -1 if an error occurs.
|
|
In the case of an error, ::errno contains more details.
