The pblock_findval function finds the value associated with a specified name in a pblock. If you want to find the pb_param structure of the pblock, use the pblock_find function.
The pointer returned is a pointer into the pblock. Do not free it. If you want to modify the pointer, do a STRDUP and modify the copy.
Parameter names are case-sensitive. By convention, lowercase names are used for parameters that correspond to HTTP header fields.
