+ GLOBAL FUNCTION
-SYNOPSIS
+ fetch_core_registers -- fetch current registers from core file
- void fetch_core_registers (char *core_reg_sect,
- unsigned core_reg_size,
- int which, CORE_ADDR reg_addr)
+ SYNOPSIS
-DESCRIPTION
+ void fetch_core_registers (char *core_reg_sect,
+ unsigned core_reg_size,
+ int which, CORE_ADDR reg_addr)
- Read the values of either the general register set (WHICH equals 0)
- or the floating point register set (WHICH equals 2) from the core
- file data (pointed to by CORE_REG_SECT), and update gdb's idea of
- their current values. The CORE_REG_SIZE parameter is ignored.
+ DESCRIPTION
-NOTES
+ Read the values of either the general register set (WHICH equals 0)
+ or the floating point register set (WHICH equals 2) from the core
+ file data (pointed to by CORE_REG_SECT), and update gdb's idea of
+ their current values. The CORE_REG_SIZE parameter is compared to
+ the size of the gregset or fpgregset structures (as appropriate) to
+ validate the size of the structure from the core file. The
+ REG_ADDR parameter is ignored.
- Use the indicated sizes to validate the gregset and fpregset
- structures.
